Hi All,

I am getting ABAP runtime error CALL_FUNCTION_NOT_FOUND when i monitor tcode ST22.

Details are as below:

Function module "/SSF/CALL_SUBROUTINE_RFC" not found.

An attempt was made to execute the CALL FUNCTION statement in program "SAPMSSY1". The name of the function module to be called is "/SSF/CALL_SUBROUTINE_RFC". No function module can be found named "/SSF/CALL_SUBROUTINE_RFC" however function modules are listed in the Function Library (SE37). Possible causes: a) Wrong name specified. Pay particular attention to upper/lower case and to underscores ("_"). or b) Transport error c) If the module is an enqueue/dequeue module, the lock object might not have been activated (Data Dictionary).

For the issue you can consider SAP KBA 1856928 - ST22 dump appear CALL_FUNCTION_NOT_FOUND - SAPLE2 _CCDB_FUNC - Function module "/SSF/CALL_SUBROUTINE_RFC" not found with Solution Manager

and follow


  • Function module "/SSF/CALL_SUBROUTINE_RFC" belongs to package "/SSF/" which is part of ST-A/PI component
  • ST-A/PI is missing on managed system
  • For instance, ST-A/PI may be missing following an upgrade of the managed system

Hope this will help you.
