SAP Business Workflow (BC-BMT-WFM)

Function module that can be used to prevent a linkage being triggered when an event occurs.

It is called synchronously in the Logical Unit of Work (LUW) of the event creator by the event manager directly before the receiver function module is called if:

• An active linkage was established.
• The name of a check function module is specified.

The check function module has the same interface as the receiver function module. This means that the content of the event container can be checked and the calling of the receiver function module prevented. If the check function module terminates with an exception, the receiver function module is not called and the linkage between the event and the receiver not created.
