Re: Bapi to post two FI documents in MB1B.

Hi,

It seems you are trying to put commit work statement inside Update task. System throws a dump when you put commit work statement inside update function module. 

Remove the statement

   CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'

            EXPORTING

              WAIT          = 'X'.

         IMPORTING

          RETURN        = return

                 .

       WRITE: /'BAPI cal worked'.

You can separately add the FI document after the material document is created. By calling :

1) BAPI   CALL FUNCTION 'BAPI_ACC_GL_POSTING_POST'  in background task  in the exit.

2)  Or create a wrapper FM . Call that FM in starting new task. Use  while and wait statement to check whether document exists in the database (MKPF). If yes, call the BAPI 'BAPI_ACC_GL_POSTING_POST'. Disadvantage of this process is that , it  opens a new session. If number of open session is more than 6-7( maintained in profile parameter) update fails.
