Business Transaction Events (BTE)

What is a BTE


BTE are comparable to the old enhancements
BTEs are used mostly within FI
BTEs can be used both by SAP, third party vendors and customers. Each use their own function modules where the logic is placed, so they don't interfere with each other

There are 2 types of BTE:


Publish & Subscribe interfaces. Can not update data. Possible to have multiple implementations
Process interfaces. Can update date. Only one active implementation


How does it work
The BTE is a function module (Implemented by the customer) that has a standard interface defined by SAP. The BTE is called by the SAP standard program by a call to function OPEN_FI_PERFORM_ or OUTBOUND_CALL_. This function checks if there are any active BTEs according to customizing.


How to find a BTE
Search the source code for for "OPEN_FI_PERFORM" og " OUTBOUND_CALL_"
Use transaction FIBF menu Environment->Info System (P/S ). Use the Documentation button to see the documentation for the BTE


Implementing a BTE
Goto transction FIBF menu Environment->Info System (P/S )
