In this example, data from an SAP ERP system, or rather R/3 system is
integrated into an Intrexx CRM using external data groups. At least
a "View Only" license for the Connector
for SAP Business Suite is required for this. Writing scenarios require
the licenses "View & Write" (
e.g. functional calls) or
"Developer API" (complete data group functions
such as create, modify, delete). The ERP Mini-CRM demonstrated here will
have the following functions:
Because we're only reading data from SAP and not writing to it, the SAP table
"KNA1" can be integrated using the datahandler
"Generic View". The required data fields from SAP
can be selected on the "Data fields" tab.
By clicking on "Add",
a dialog is opened where the following data fields should be selected:
The "LID" data field is a generated help field
that contains the entire SAP key of the data set (without client). This field
should always be selected. By clicking on "OK"
the data fields are connected. Adding more fields can be done at any time.
The texts for all of the
configured in the Intrexx portal are identified in SAP in this step
and the corresponding titles are applied. With a final click on "OK",
the SAP external data group is created. The name can be changed to
"SAP" by double-clicking on the new data group.
The new view page is created by clicking on "OK".
A view table is now created on the page and the SAP external data group is
selected in the
By clicking on "
Add columns", data fields can be selected whose values are listed in a
respective column in the table.
By clicking on "
Sorting", the table can be sorted by name.
The setting is applied with a click on "OK".
The properties dialog is also closed by clicking on "OK".
The table is now finished.
The new view page should be available via the application menu in the browser.
After double-clicking on the Application node,
the properties dialog of the application is opened. On the "
Application menu" tab, the "Customers" page
is selected and positioned. The new setting is saved by clicking on
"OK". The application can be saved and published. Once
the application has been saved, the SAP customer base is available in the portal.
3.3. Research in the customer base
Searching by customer number and starting letter is set up using
3.3.1. Operator filter - Search by customer number
On the "Customers" view page, a dynamic filter
(Operator) is added above the table. On the "
Comparison" tab in the properties dialog, the operator
"Begins with" is selected. Additionally, the
data group "SAP" and the data field
"Customer" are selected.
The setting "Show list with operators" can be deactivated
on the "Miscellaneous" tab. Filter is created
by clicking on "OK". Now, the
dependency needs to be
defined for the table. To do that, the
properties dialog of the table
is opened and the "Dependencies" tab is selected.
By clicking on "
Add dependency", another dialog will open.
The control can be defined that the filter reacts to by clicking on
The Operator filter and the event "onchange"
are selected here. The new setting is applied with "OK".
A filter expression needs to be formulated now. This is done with
"Add new filter expression".
Here, the field "Customer", the operation
"Is contained in", the control "
Operator", which serves as the search field, and the comparative data field
"Customer" are selected. The new settings are
applied with "OK".
The dependency is now created. The dialog is closed by clicking on
This dialog can also be closed with "OK".
The filter is now created.
3.3.2. Alpha-index filter - Search by customer's first letter
Now, the second filter for searching by the customer's first letter will
be defined. The "Alpha-index" filter will be
used for this.
The settings here can be left as they are and applied with
The additional filter expression can be created by double-clicking on the
"Edit dependency" here.
The Alpha-index filter is now added as a triggering control here.
The new filter expression is defined as: Name starts with
"Alpha-index". You can see the
details of the filter expression's properties below:
The new settings can be applied with "OK"
and the application can be saved.
In the browser, the users can now search using a combination of the customer
number and name. In this example, a search has been made for customer numbers
beginning with "0000" and customer names beginning with A-D. There are of course
other options for filtering by the customer name. You could, for example,
configure this like the customer number filter so that all customer names
are found that begin with a specific character string.
4. Detailed view - Customer data sheet
4.1. Create detailed view
In the next step, we will created a detailed view for the customers which
can be opened from the view table on the customer page. By the way:
The customer page can be defined as the start page for the application
Main menu "Edit / Start page" if it
is currently selected in the
Via the context menu "New / View page with elements",
a view page can be generated with all of the integrated data fields
from the SAP external data group. The title is changed to
"Customer data sheet" here.
Redundant view elements can be deleted. If you would like to provide
more data on this page, such as ZIP code and city, the corresponding data
fields need to be included in the
SAP external data group.
A button that links to this details page is added in the properties dialog
of the view table on the "Customers" page by clicking
on "Add column". The target destination
"Customer data sheet" has already been selected
correctly. Click on
"Edit column" after selecting the button column.
On the "Actions" tab, you can define that the
customer data sheet is opened in a tooltip when a user clicks on the
button in the table. Apply all of the settings by clicking on
"OK" and then save the application.
In the browser, the customer data sheet will be displayed in a tooltip
by clicking on the button.
4.2. Display orders in the customer data sheet
To display orders for the customer in the customer data sheet we will create
another external data group that integrates the SAP table VBAK
(SAP task information).
Switch to the "Data fields" tab.
All of the required data fields from the order header can be selected
here. Apply all of the new settings by clicking on "OK".
The external data group "SAP orders" has now been
created. Now, a filtered view table for the customer orders should
be created on the customer data sheet.
The external data group "SAP orders" is selected
in the properties of the view table. The, select the required
data fields for the table columns by clicking on
column" and sort them with the aid of the
arrow keys. Finally, open the filter dialog by clicking on
Click on "
Add new filter expression". Select
"Sold-to party" as the data field and
"Equals" as the operator. The data field
should be compared with the value from the data field
"Customer" on the current page.
If the values match, the table will display the orders where customer
number of the currently displayed customer data record is saved in the
"Sold-to party" data field.
Click on "OK".
The first part of the filter expression has now been defined. Furthermore,
the results displayed should be restricted to the sales document category
C. This category is used for orders. Without this restriction, every document
would be shown where the customer is defined as the sold-to party.
"Add new filter
The second part of the filter expression has to be created with an AND
join. An OR join would display every document category of the sold-to
party OR every document with the category C. With the AND join, both
conditions are applied to the available data, meaning that only
documents with the current customer as the sold-to party AND with the
category C are displayed. The data field "SD document categ."
is entered here with the operator "Equals"
and the user-defined character string "C".
Click on "OK".
The filter expression is now finished.
Apply all of the new settings by clicking on "OK"
and then save the application.
The orders are now shown in the customer data sheet.
5. Display contact persons
5.1. SAP external data group for customizing table
A new SAP external data group, which contains the customizing table for the
"Department" field, is created
via the application node.
Our SAP database connection is selected once more. The customizing table
"TSAB" is integrated as the table.
The SAP portal plugin immediately breaks customizing tables down
into the connected text tables. Information about how this
behavior can be avoided can be found in the
SAP API Developer's Manual.
On the "Data fields" tab, the required data fields
can be selected as usual.
5.2. SAP external data group for contact persons with reference
The master data table "KNVK", which contains
the data for the SAP contact persons, will be integrated into the application.
The data fields needed can be selected on the
"Data fields" tab.
Click on "OK".
The field "ABTNR", or rather
"Department", will now be added to the
"SAP departments" data group created earlier
as a reference. To achieve this, double-click on the new
data group "SAP contact persons" and switch to the
"Add reference" to create the reference.
Enter "Department" as the reference title.
to enter this title in the other portal languages.
The "SAP departments" data group is referenced (
corresponds to the SAP customizing table). Click on "Next".
Now, click on
"Edit". Then, select the
"ABTNR" data field that contains the
SAP coding. Click on "OK".
The assignment is now created.
Click on "Next".
Here, you can select which fields from the customizing table should be
visible to the users. Select the field that contains the description text
for the coding.
Click on "Finish".
The reference is now complete. General information about
"references" can be found
5.3. Adding the contact persons to the customer data sheet
We will now added another view table to the customer data sheet.
The referenced deparment field can also be integrated as a table column.
If you would like to change the name of a table column, select it and then click
on "Edit column".
The order of the columns can be edited with the
arrow buttons. The access to the SAP contact person now needs to be restricted
to the current customer with a filter. To do that, click on
Here, click on
"Add new filter expression". The
"Customer" data field should be compared
with the current value from the "Customer"
field in the "SAP" data group with the
"Equals" operator. This means that the table
loads the data records where the same customer number is stored
in both fields. Confirm your settings with "OK"
and then save the application.
To make it easier to tell the difference between the tables in the browser,
you can define a table in each of the
and then activate the setting
Once the application is saved, the title will be shown in the browser.
6. Customer correspondence
6.1. Enhancing the application template
Add a new edit field
to the "New document" edit page. Select the option
to create a new data field at the same time.
Click on "Next".
This field will be used for the customer search later. Its title is "Customer".
The control type
is text and the
data type is string.
Click on "Next" on the subsequent dialog pages and
leave all of the settings as they are until the element is finished and created.
Another edit field for the SAP customer number is now created. Users may
not enter data into the field. However, a data record is only valid
when a customer number is in this field.
Its title is "Customer number".
The control type
is text and the
data type is string.
Click on "Next" and then on "Finish".
The settings "Read-only" and
"Input required" are activated here.
Click on "OK".
6.2. Customer search via Data Picker
The user should be able to search for a customer by typing their name,
either entirely or in part, in the customer field and then by selecting
them from a suggestion list. A
button with the
action performs this action. Once the user selects the customer, the customer
number is automatically written to the customer number field.
The button is defined as an image here. By clicking on
a suitable image can be selected for the button when the mouse is over
it and when not.
Click on "OK".
The image for the button has now been defined. Switch to the
"Data Picker" can be selected as the action type here.
The customer field is selected as the search field. The search should be performed
in the current application in the "SAP" data group
which contains the customer data. "Name" is selected
as the data field. At the bottom, the "Customer number"
field can be mapped to the "Customer" field
from the SAP external data group. This means the customer number is taken
from the SAP external data group and copied to the
"Customer number" edit field on our edit page.
The data group selected for the search can be restricted by clicking
for example to remove undesired results such as data marked for deletion.
Click on "Advanced"
to open a further dialog where the appearance of the list, which displays
the search results to choose from, can be defined. At the top, you can specify
which fields should be shown to the user in the search list so that they can
make their choice. The number of results shown can be restricted at the bottom.
With the "Show navigation element" setting, the
user can navigate through a longer list of results. More information
about the settings in this dialog can be reached by pressing F1. Usually, the
user has to click on the Data Picker button to trigger the search function.
The search function can also be triggered automatically when a specific number
of characters have been entered. This behavior is controlled by the setting
"Show results with an entry length of at least ... characters".
In SAP, this setting can be relevant for performation and it is better to select
a number that's too high and to limit the results with filters.
Confirm your settings by clicking on "OK".
The size of the button can be automatically adjusted to the
original size of the image selected by selecting
"Set full size" from the context menu.
6.3. Adding the new fields to the view page and search
In the previous, the new data fields "Customer"
and "Customer number" were added to the Intrexx
data group "Documents" along with the
corresponding edit fields. The contained data will now be shown
in the view table "All documents" and also added
to the search configuration for the search.
Open the view page "All documents" and open
the properties of the view table by double-clicking on it.
You can add the two fields by clicking on
"Add column". Save the changes by clicking on
"OK" and then switch to the
On the "Search" page, open the properties of the
button by double-clicking on it. Then click on
Edit search configuration" and then
Edit search configuration" in the subsequent dialog.
Activate the setting "Search" at the bottom
of the dialog for the fields "Customer"
and "Customer number". Apply all of the new
settings with "OK" and then save the application.
6.4. Test the application
A test dataset can now be created on the "New document"
page. "Mega" will be entered in the customer field and then the Data Picker
button will be clicked on. Because there are multiple hits, a list will
be shown from which the correct customer can be selected.
When you select a customer, the correct name is automatically in the Customer
field and the correct number in the Customer number field.
Click on "OK" to save the new dataset.
The new dataset can now be seen in the table on the
"All documents" page.
You can search, for example, for the customer number on the
"Search" page. Hits will be shown beneath
the search field when you click on "Search".
Click on the title link of a hit to load the
"Call up document" page where the dataset
can be viewed.
7. Create simple master data list with SAP Reports
A simple method of presenting SAP information as master data sheets
is provided by the report integration of the Connector for SAP Business Suite.
Proceed in exactly the same manner as shown earlier in the previous chapters
and create an external data group for SAP Reports.
In the properties of an external data group, select your SAP connection
as usual. Select the data handler "Generic Report"
and enter the technical name of the report in the Table/View field
(e.g. in the code example below
"zz_demo_ixapi_report"). Intrexx accesses SAP
via the Generic Report data handler and transfers the parameters and
generated lines of text. The scaffolding of the SAP reports contains
simple PARAMETERS instructions that are then available in Intrexx as
filter criteria. The following example contains the material number
as the parameter for which information in SAP will be acquired in
the START-OF-SELECTION section.
report zz_demo_ixapi_report no standard page heading line-size 256.
* ------- interface
parameters matnr type matnr.
The complete coding of this example can be found
8. Possible extensions
8.1. Filter criteria from the user context
In some scenarios it makes sense to use additional filter criteria to
restrict the number of hits for authorization reasons.
Examples for filter values from the user context are
In a customer portal, for example, the view of your own orders could be
automatically restricted to the customer number from the user account
(filter expression: Sold-to party = Current user - Customer number).
8.2. Personalized access
An SAP system is accessed by at least one system user, who is configured
in the settings of the SAP data source. However, it is also possible to work
with the SAP user of the portal user. To do this, enter the
as an expert attribute
in the properties of the SAP external data group.
8.3. Improved search
Searching using the SAP customer base,
as implemented in the example application, is case-sensitive (a distinction is made
between upper and lower case). If this is not taken into account in the search term,
or if the search term can be found in another field, e.g. if you search for the
postal code instead of the name of the customer, no results are obtained. To
optimize this state, you can implement your own handler in the SAP portal plug-in.
A sample code can be found here.
8.4. Display an optimized internal SAP table
Deleting SAP-typical codes
via a reference,
as in the previous example, is not always technically feasible in this way.
The resolution of texts for a large number of fields can also lead to
performance problems. In some cases, the data in SAP is distributed across
several dependent tables, so it is hardly possible to form a join across
all the tables required. In such cases, it is quite possible to build the
data in SAP as a typical internal table and only then integrate it into the portal.
The API methods
GET_LIST and GET_DETAIL
must then be implemented for read-only access. For an example of how internal
SAP tables can be made available, see
8.5. Replicate SAP data in Intrexx data groups
As an alternative to external data groups, SAP data can be written to Intrexx
data groups via a process.
To begin with, a new Intrexx data group is added to our example application.
The data from the SAP external data group SAP,
where customer data from SAP is integrated, should be replicated
in the new Intrexx data group via a process. Before the application
is saved, the data type of the primary key field "ID"
needs to be changed to "string" to be able to use the SAP customer number
as the primary key in the Intrexx data group. Switch to the
"Data fields" tab.
A data group action
is now connected to the timer event handler. The action will delete
data records. Click on "Next".
Select the SAP application and then the "Customers" data group.
Click on "Next" and leave the subsequent settings as they are.
Based on the same principle, create a second
global timer and
set the execution time to 08:00.
Select the SAP external data group "SAP".
Add a new timer event handler and select the second timer here.
Connect a data group action to the handler. This will transfer the
data from the SAP external data group to the Intrexx data group.
Select the option "Add record" here.
The target data group is the Intrexx data group "Customers".
The primary key and the remaining fields are assigned here.
The process is immediately activated once the process is saved.
To prevent the process from running before it has been tested properly,
it to begin with. Both timers can be started manually for testing purposes.
In the Tools
module, open the
and find the timer actions in the list of tasks. Use the
context menu to start the
corresponding timer manually.
8.6. Generic writing to a Z table
There is often a requirement to convert a new BusinessObject for SAP. This
means that Z tables and a user interface (for example, simple table
maintenance) are implemented in SAP in the customer namespace. The method
described here is one way of implementing the data model in SAP and mapping
the user interface completely in Intrexx. A sample code for the corresponding
data handler (derived from Generic View Handler) can be found
The data handler is registered as GENERIC_WRITE. A table with a GUID key
field of technical type RAW(16) is required. This can refer to data element
ZIA_IXA_GUID or SYSUUID_X, for example. It is easier to use a GUID than
number ranges, since the Global Unique IDs (GUID) created with the SAP
function module GUID_CREATE are unique worldwide. As of SAPPOPI Version
2010, the data handler GENERIC_WRITE is part of the package. This version
also removes the restriction of the GUID key field. Data records with a
simple key can then be changed and deleted. However, it is impossible to
insert new data records without adjusting the handler, since the handler
has no knowledge of the logic of new keys.
If you have created such a table with the GUID key field (and the client field), the table must be registered in the mapping of the SAP Portal Plugin. As of SAPPOPI 2010, registration is no longer required.
The table can then be used immediately as an external data group
of the Developer API with full access in Intrexx.
All functions such as create, change and delete are available for the
Developer API objects and the "Generic Write" handler.
8.6. Display documents in the portal
In SAP, documents (for example, drawings, correspondence, invoices)
are available in three different ways:
As a document in the archive system (or in KPro)
As a document in the file system or accessible via an FTP server
As a document in the SAP database (for example, cluster tables, BLOB fields)
If one wants to make these documents available to the portal user, it must
first be generally clarified whether direct access by external users to the
documents from points 1 and 2 can and may be made possible. Point 3 is
excluded here, since direct read access to the SAP tables is generally not
possible here. If direct access from outside is technically possible, you
can work with a URL. It does not matter whether the data comes from the
archive system or is already in the file system. It is only important that a
web server, which delivers the documents, exists and is accessible for the
portal user. The task of the SAP system is solely to generate the
corresponding URLs, which are then displayed in the portal as buttons or
links. A sample code for generating the URL for archive documents can be found
If the files are on a network drive (point 2), the coding is similar. In this
case, however, the URL must be generated that corresponds to the network
drive from the portal's point of view. The data handler
GENERIC_ARCLINK can be used for this. If
technically possible (e.g. under Unix), the network drive can be mounted
in a sub-path to the portal, e.g. as directory docs under the
portal directory external/htmlroot.
The documents are then available to the user at
http://<host>:<port>/<portal>/docs/*. If the user cannot access
the documents directly, the documents must be provided on a path accessible to
the web server. Technically, the documents must then be read on the SAP
application server and copied to the externally accessible path. The easiest
way to do this is with the SAP ABAP command OPEN DATASET ... TRANSFER. If
only FTP is available for file transfer, the SAP programs RSFTP* demonstrate
how to use the FTP protocol. You can also use
to exchange files between the SAP application server and the portal server
using the RFC protocol. For many documents (e.g. all invoices for one user),
not all documents should always be replicated. The handler methods in
GET_LIST and GET_DETAIL can be separated here. The list view would create an
overview of the available documents based on the filter criteria. Only branching
to the detail view must trigger replication to the Web server. To do this,
the sample code
must be extended by the API method GET_DETAIL, which initiates replication
in addition to formatting the data.--> For security reasons, the file names
can be encrypted. The SAP function module GUID_CREATE is suitable for this.
An invoice 1204387.pdf becomes 81C0C8484EB3A637E100000000C0A8DEE6.pdf.
Security is further enhanced if these files are automatically deleted
after a certain period of time.
8.7. Change SAP objects
Changing access at table level would be technically possible, but is not
supported by the SAP Portal plugin. The
developer manual for the plugin
contains an example of how to deal with SAP objects. In principle, it must
be possible to represent the SAP object in a transfer structure. Then all
desired methods (e.g. Modify, Delete) must be implemented in the API. In
these methods, the transfer structure is mapped and processed to available
BAPI functions. The BAPI functions always contain the lock concept.
8.8. Document flow to portal objects
Document flows can be mapped in Intrexx without any problems. However, if
document flows are also to be mapped to external objects in the SAP System,
you must proceed differently here. In principle, pages of the portal can also
be included in SAPGUI transactions. To do this, a special URL is called that
branches to a detail page for the object. The key of the object is encrypted
in the URL. So that external objects can be called from the SAPGUI
transactions (for example, document flow), a BusinessObject is required that
implements a DISPLAY method and generates a view of the portal when generated
by the SAP standard. The document flow between SAP and non-SAP objects is
generated using standard SAP functions. In SAP transactions, you can usually
double-click on the BusinessObject using the DISPLAY method.
9. Special concepts
9.1. Expert attributes for SAP external data groups
Expert attributes are used in Intrexx applications to provide additional
configuration options that are not or not yet available in the
properties dialog. Information about the Expert mode can be found
For example, the expert attribute "bia-handler" specifies the SAP
data handler to be used (e.g. "GENERIC_VIEW"). The additional expert
attribute "bia-loginuser" controls, for example, whether access to the
SAP system should be personalized. A list of other available attributes
and their use can be found
These expert attributes are used in relation to the data group
(e.g. "bia-forcefilter = <true|false>" forces one or more filter
criteria) or to the contained data field
(e.g. "bia-KUNNR-numkeylen = <len>" maps the data depending on the
direction with and without leading zeros in the specified length).
If a setting is to refer to a data field, the expert attribute must be
entered in the naming convention "bia-<Name of field>-<option>".
The expert attribute is then called "bia-<option>", since the data
field name is always given.
9.1.1. Generic View: "nolangtab" variant
The most frequently used data handler "Generic View" has been implemented so
that the linked text table is automatically determined when customizing
tables are accessed and only the texts in the portal logon language are
transferred when the data is selected. In most cases this has made work
easier. However, some Customizing tables contain interesting additional
information that was no longer available. There was a workaround to use
these leading tables, but it was cumbersome and had to be configured in
the SAP system. This is compounded by the fact that some very important
tables in the SAP System look technically like Customizing tables (for
example, table "MARA"). Therefore, the handler "Generic View" in the
variant "nolangtab". This variant prevents access to the text tables and
thus allows access to tables such as "MARA" without great effort.
9.1.2. Generic F4
The "mapcodefield" expert attribute can be used to
the codes used in certain SAP fields into meaningful SAP F4 help texts.
The "Generic F4" data handler provides these F4 helps as a simple code
text table in the logon language of the portal. This means that list boxes
of dynamic filters, for example, can be filled without major problems.
<SAP DDIC structure or table>-<table field>" is expected as the
table. Unfortunately, determining the F4 texts is not always easy. Therefore,
this cannot be supported for every field. However, you can also support
special cases using the inheritance concept of the SAP data handler class.
9.1.3. Generic ArcLink
This handler enables access to archived documents that are assigned to
an SAP object. The SAP data handler would determine the archive documents
for the specified SAP BusinessObject and the corresponding object ID and
make them available as a table. This table contains a "URL" field that
contains the URL to the archiving system (SAP server or external solution).
This URL field can be transferred to another (e.g. hidden or external)
display using the expert attribute "bia-mapurl". The purpose of this handler
is in any case to provide easy access to documents (e.g. order confirmation
as PDF) via the direct path of the URL.
The handler expects the SAP BusinessObject (such as VBAK) as the table
or the character * for generic access. In any case, the ID of the SAP
object (for "VBAK" the document number "VBELN") must be specified in the
filter. The SAP BusinessObject is also expected for generic access (*).
You can provide the ID of the SAP object very easily using dynamic filters.
In the expert attributes, you can also set here that
the object ID is automatically converted to a 10-digit numeric key
("bia-OBJECT_ID-numkeylen = 10" option) and
the data group requires a filter ("bia-force filter = true")
9.1.4. Generic text
This data handler provides generic access to long texts in SAP (table STXH).
The text object must be specified as the table name (e.g. BUS2032).
Generic access with the * character is possible here if the text object is
available via filters. The data handler returns the "STXH" table,
supplemented by two fields that contain the actual text. A long text
is automatically generated with the unformatted text ("TEXT_NORMAL" field)
and with HTML formatting ("TEXT_HTML").
These fields can then be included as usual on a view page.
9.2. Permissions for own data sets for SAP external data groups
In conjunction with external data, it is not easy to determine when the
available data records are your own data records. This problem and its
solution will be demonstrated using the example of the SAP order header
data (table "VBAK"). Depending on the context of the portal user, there
are fields in this SAP table that can be used to identify your own data
records. From a customer's perspective, for example, this is the SAP field
"KUNNR" (customer number), which must be populated with the customer number
for their own data records. From an internal employee's perspective, however,
it could be the SAP field "ERNAM" that contains the SAP user of the order
creator. The second challenge is to determine the values to be checked in SAP
(for example, customer number, SAP user name or personnel number).
The required mapping between the user logged in to the portal and the SAP
value to be checked can be performed in many different ways. The simplest
option is to create your own attribute value using the
in the Intrexx user manager
and to maintain such values as the SAP customer number here.
Such an attribute can be used as a filter value for view tables,
for example. This allows you to control the permissions for SAP data
in lists. However, the application permissions for data groups are
not yet evaluated here. This therefore does not prevent direct navigation to a
detail page that is not permitted. A concept called "Permission Filter"
is used here. You can imagine the effect as a permanent filter directly
applied to the external data group, which is also used when displaying
the detail pages and thus prevents the loading of non-permitted pages.
A simple application that implements access to the SAP "VBAK" table
is used here as an example. Access will be restricted via application permissions.
Own data records are interpreted as SAP data records that
have the value from the user attribute BIASAP_KUNNR in the "Sold-to party"
The SAP table "VBAK" is now added to the "All Entries" page.
Here, the external data group "SAP order data" and the desired
data fields are selected for the table.
Then create a filter
that compares the data field "Sold-to party", which contains
the customer number in SAP, with the value from the user attribute
Save the application and publish it in the menu structure.
Afterwards, determine the application GUID
by selecting the application node
and by pressing F4.
Open the portal directory
and navigate to the folder "internal\application\store". Open the folder
with the same name as the application GUID and open the file
"application.xml" with a suitable editor (e.g. Notepad++).
Close the application now. The changes in the next step cannot be saved
unless the application has been closed.
In the section "viewpage", search for the filter we just created.
This section is after "tablecontrol".
Cut the entire area <filter> … </filter> and keep this on
the clipboard. Now search for the external data group
"SAP order data" in a "datagroup" section. After the "property"
section but before the "datafield" section, add a new section
Paste the copied filter section into this permission section.
Save the modified XML file. Then reopen the application in Intrexx. There
should now no longer be a filter the properties of the view table. Via the
context menu, show the data fields from the external data group
"SAP order data".
The permission filter should now be shown under the data group.
Open the properties of the application by double-clicking on the
and switch to the "Application permissions" tab.
Provide the permission "Read data set (own)".
Save the application. Afterwards, all accesses made to the data group
and its detail pages will be restricted accordingly.
