Effect

Calls the function module specified in func.

Additions

• IN UPDATE TASK
  Registers an update function module.
• DESTINATION, STARTING NEW TASK, IN BACKGROUND UNIT, IN BACKGROUND TASK
  Synchronous, asynchronous, background, or transactional RFC (obsolete).
• {CALLING meth}|{PERFORMING subr} ON END OF TASK
  At the end of an asynchronous RFC, calls method meth or subroutine subr.
• EXPORTING p1 = a1 p2 = a2 ...
  Passes actual parameters a1, a2, ... to input parameters p1 p2, ...
• IMPORTING p1 = a1 p2 = a2 ...
  Inherits output parameters p1, p2, ... in actual parameters a1, a2, ...
• TABLES t1 = itab1 t2 = itab2 ...
  Assigns internal tables itab1, itab2, ... to table parameters t1, t2, and so on.
• CHANGING p1 = a1 p2 = a2 ...
  Assigns actual parameters a1, a2, ... to input/output parameters p1, p2, and so on.
• EXCEPTIONS
  Enables the handling of non-class-based exceptions:
  
  exc1 = n1 exc2 = n2 ... - Assigns numbers n1, n2, ... to the classic exceptions exc1, exc2, ... for the return code sy-subrc.
  
  error_message = n_error - Handles messages using the special exception error_message.
  
  system_failure, communication_failure, resource_failure - Handles special classic exceptions by passing the first line of the short dump to smess or cmess.
  
  OTHERS = n_others - Assigns a number n_others for the return code sy-subrc to all exceptions not named explicitly.
• PARAMETER-TABLE ptab
  Assigns dynamic actual parameters to formal parameters using an internal table ptab of the type ABAP_FUNC_PARMBIND_TAB.
• EXCEPTION-TABLE etab
  Assigns dynamic return codes to non-class-based exceptions using an internal table etab of the type ABAP_FUNC_EXCPBIND_TAB.
