Check an existing connection to the SAP system "p_instance" in login mode "p_loginmode". If "p_connect = true" and not yet connected, a connection is established.

Close a connection to the "p_instance" SAP system

Close a connection to the SAP system ""p_instance"" of the user

Establish a connection to the "p_instance" SAP system

Establish a user connection to the SAP system "p_instance" with user/password

Set the login information via a token for an SAP system manually. The token (e.g. SSO ticket) contains parameter "p_token". Depending on the type of token, the parameter "p_method" must be set (e.g. "MYSAPSSO2" for SSO ticket)

Set the login information username/password or a user from the current sessions manually

Reset the login information for a user (e.g. SSO ticket information, for user switch)

Integrating this function in Velocity enables you to use the SAP interface of the utilizing page. SSO initializations are performed and SSO JavaScript functions are made available, for example. The "p_request parameterr expects the Velocity-$Request object to be transferred. The "p_mapurl" flag controls the mapping of SAP URLs.

Using this function in Velocity integrates an SAP web interface as an iFrame. The call requires the "ssoPrepare" function on the same page in order to execute the necessary JavaScript functions (e.g. set SAP ticket, initialize URL mapping). URL mapping is activated via the active flag "p_mapurl".

This function enables you to log in to the Intrexx portal via an Intrexx page (anonymously). Once the login is successful, a session ID will be returned.

Starts the SAPGUI for the specified SAP data source as a transaction in the specified login mode (usually "user"). Additional parameters (e.g. fields to be filled) are included in "p_extra". The start screen can be skipped with "p_skip = "true"". The "p_url" flag controls whether an evaluation of the portal URL is necessary (e.g. different SAP router strings). To do this, however, the page must have been initialized with "ssoPrepare" in Velocity.

Like function "biasap_start_transaction_url" without URL evaluation

Starts a report in the specified SAP system with or without variants. The "p_url" flag controls the customization of the path to the SAP system via the portal URL.

Like "biasap_start_report_url" without URL evaluation

Set a cookie (e.g. for SSO)

Determine a cookie

Delete a cookie

Set the SSO ticket for SAP web interfaces. If it is not possible to determine a valid SSO token and an error message is available via "p_message", this error message is displayed. The parameter "p_cancel_on_error" controls whether an erroneous ticket should cancel the processing of the script and also the subsequent scripts (e.g. for buttons) (effect: no display of the SAP web interface if the ticket is incorrect).

This method initializes the SAP OCI functions of the Connector for SAP Business Suite. This method is intended for integration on a view page (Velocity). The current session and the request are transferred. The third parameter defines which authentication method should be used. The default setting is "PlainAuth", which must be configured in the portal. A login to the portal is performed with the transferred parameters and the received parameters are checked for validity for SAP OCI. The result is boolean. If it has the value "true", the login was successful. With the value "false", the logon was either incorrect or the transferred parameters are not valid for SAP-OCI.

This function checks whether a valid SAP OCI session is active. Use this function to adjust jump targets in the application, for example, if the application is not only used for SAP OCI scenarios.

This function returns an HTML text that contains the current OCI information. The function can be used to present technical OCI information quickly.

With this function, a specific value can be identified from the OCI data. With "$!GSAP.ociGetInfo("vendor")", for example, the vendor number can be read out and used as a default value for input fields. Possible values for "p_info" are:

• sapuser
  

  Technical name of the logged-in SAP user

• login
  

  Login name for the portal

• domain
  

  Login domain for the portal

• customer
  

  Customer number of the purchaser at the vendor

• vendor
  

  Supplier number at the vendor

• oci_version
  

  OCI version

• opi_version
  

  OPI-Version

Sets the return address after sending. A button is expected to be transferred. A button is expected to be transferred.

Generates the most important transfer data for a shopping cart item (the "row" line)

Generates more data for a basket item. The technical name of the OCI specification is expected in "name" (e.g. "VENDORMAT")

Generates a longtext at the position

Generates a another transfer field stating the technical name

To initialize the SAPGUI from the portal

Diverse JavaScripts with utility functions

Adjust the timezone for time stamp fields. SAP systems often run in the CET timezone, Intrexx in UTC on the server. This causes displacements when times are being displayed. However, it is better to define the timezone in the configuration of the data source (attribute in the file sap.cfg).

Login mode for SAP access (<system>|<user>|<mixed>)

Handler for SAP access (e.g. "GENERIC_VIEW", "DEVELOPER_API")

Variant of the SAP handler (e.g. "DEFAULT"). Can be used for a divergent identification of the SAP datahandler

Option to transfer controlling parameters to the SAP handler. The values are available in the CONTROL structure in the SAP datahandler.

Option to activate the debugging for the pertaining external data group only. "True" activates debugging. SAP debugging is only possible if the portal is running on your own computer and a SAP GUI is installed.

This parameter (active = "true") can be used to control that no data is determined for table accesses if no filter is active. This prevents hidden tables from being accessed in the SAP system in conjunction with dynamic filters.

Activates the trace for this data group. Extended messages for this will be provided in the logfile in doing so.

Contains a specification of which version of the business logic is required to avoid errors in advance (use of new features).

bia-simplekeyBooleanDG For SAP data groups with complex keys (e.g. VBAP), only a count from 1...n is used as the key for simplification reasons. A link to a details page is not possible here. However, this option can simplify access to cells within a free layout table.

If this option is activated, the data is cached on the server. If the data in the SAP system changes, only the old data is displayed in the portal. The option is especially well-suited for customizing tables that are used as references (performance). The server-side cache can be reset by closing the connection to SAP.

This option is only relevant in the datahandlers for the Developer API. The SAP API method "Get_Detail" would not normally be called for new data records. However, this can be forced with this option to preallocate values from SAP.

This option is also only relevant within the Developer API. New data records are generally given the ID -1 by Intrexx. With this option, this default key is deleted. In SAP, it could be queried with "if iv_key eq space".

As an alternative to the corresponding bia-variant, this option activates that the text table is not determined automatically in SAP. This allows problem cases such as the table MARA to be displayed in the portal with reasonable effort.

This option activates that specific data is transferred as HTML code instead of normal text. This option is used, for example, in the "Generic Report" data handler to transfer an SAP report in the SAP-typical colors.

This option activates the transfer of longer texts as longtext instead of multiple lines. This option is used in the "Generic Report" data handler. The report is therefore not transferred in lines and needs to be presented as a free layout table. A string field contains the entire report with this option.

This option activates an automatic mapping of SAP-typical numberical keys. Via the defined length, the logic of the Connector for SAP Business Suite knows that this field needs to be completed with leading zeroes when transferrring to SAP (alphanumerical keys are an exception). These fields are presented without the leading zeroes in the portal. If this option is used at data group level, the key is automatically treated as a numerical SAP ID.

This option tries to solve the problem that time stamps usually are not used in SAP but separate fields for date and time instead. Intrexx, on the other hand, uses timestamps and can also display them as "date only" or "time only". Using this option, the data field from the SAP system is informed as to which SAP field contains the corresponding time. The SAP date field becomes the time stamp in doing so and can be used as such (e.g. in calendar controls). When presenting times, the time is often displaced (e.g. 2h). This is because the SAP server and the portal run in different timezones (CET vs UTC). That is way, the SAP timezone can be configured in the data source or via bia-timezone. This function should also work the other way round (writing time stamps to two separate SAP fields). The field for the SAP date is key here as well. The corresponding time field may need to be available on the pages (hidden), however.

Encodings are often used in SAP systems (typical characters 1...6 fields; e.g. VBAK-VBTYP). These are transferred as text - meaning as SAP code - and cannot be used by the user therefore. There is of course the option to connect the corresponding customizing table in a language-dependent manner as a reference. However, this can be very complex in some circumstances. This option provides a simple possibility: the "Generic View" data handler attempts to determine suitable texts from the configured search help or other SAP mechanisms. This approach cannot be used everywhere (e.g. in more complex search helps with multiple keys).

With this option, URLS can be mapped whilst taking the portal URL into account. This is required for hiding the real URL on the SAP systems (calling archived documents), for example. An internal access can thus be mapped from "sapsystem.internesicht.net" to "archiv.externesicht.com" as soon as the user uses the external access to the Intrexx portal.

Makes the value upper-case. Useful in SAP matchcode fields.
