Call external program in background mode

Question

Hi,
I am creating a PO using bapi BAPI_PO_CREATE1 in exit USEREXIT_SAVE_DOCUMENT_PREPARE.
I dont want to write the code in my exit. Instead I want to write the code in a Z program and call it in my exit.
My Problem.
How do I call my z program in my exit so that I can pass internal tables from my exit to the z program. Also I want to schedule the call of my external program for background processing.
I am trying with SUBMIT ZPROG AND RETURN. But not able to pass an internal table.
I tried PERFORM BAPI_PO_CREATE IN PRGRAM ZPROG, but in this case not able to schedule it in background.
Please advise.
Regards,

What happened?

     The current ABAP program "ZMM_SERVICE_PO" had to be terminated because one of
      the
     statements could not be executed.
     This is probably due to an error in the ABAP program.
     When importing the object "XVBFA", the object in the
     dataset had a different type from the target object in the program
     "ZMM_SERVICE_PO" (object types: field, field string/structure, table).
