The event concept enables the integration of industry-specific and customer-specific function modules at specific points in the existing system architecture. Using installation-specific and industry-specific function modules you can enhance the standard business processes by predefined program events without modifications. Depending on the event, they can either realize alternative program logic or additional functions.

Further technical information
The function module FKK_FUNC_MODULE_DETERMINE is processed for each event.
|FKK_FUNC_MODULE_DETERMINE||Determines the event modules defined in Customizing|
From the following tables, the function module FKK_FUNC_MODULE_DETERMINE sequentially determines the event modules defined in Customizing that are to be processed:
|TFKFBM||Sample function modules|
|TFKFBS||Standard function modules for Industry solutions|
|TFKFBC||Installation-Specific Function Modules (Customer Function Modules)|
|Specifies whether several function modules can be processed in this event or a maximum of one.
>If the indicator is set, several function modules of the corresponding industry solution and several customer-specific function modules can be processed.
The modules that the application area has defined are called first, and then the customer-specific modules.
> If this indicator is not set, only one function module is called. In this case, a customer function module has priority over an application-specific function module.
|No Customer Module
|If this indicator is set, customer function modules are not taken into account for this event in the application area in question.|
You must not use the following language elements in events, unless they were explicitly declared to be allowed for the given event:
- COMMIT WORK
- ROLLBACK WORK
- CALL FUNCTION ‘DEQUEUE ALL’
- Deletion of locks that you have not set yourself
- Implicit database commits triggered by RFC calls or by a WAIT statement
