Often when an error occurs in your ABAP code, it would be helpful to display how the error occurred, in which routine or method the error occurred and how you got to this routine.
Use function SYSTEM_CALLSTACK to display the call hierarchy (for
example, in error handling). Using this function, you can show this extra
information to help analyze the problem.
This function works on a Basis system -- version 4.6 C or higher.
Code
REPORT zz_system_callstack.
* Example of using the system callstack function
DATA: ta_callstack TYPE sys_callst,
wa_callstack LIKE LINE OF ta_callstack.
START-OF-SELECTION.
PERFORM call_routine_1.
*&--------------------------------------------------------------------*
*& Form call_routine_1
*&--------------------------------------------------------------------*
FORM call_routine_1.
PERFORM call_routine_2.
ENDFORM. "call_routine_1
*&--------------------------------------------------------------------*
*& Form call_routine_2
*&--------------------------------------------------------------------*
FORM call_routine_2.
CALL FUNCTION 'SYSTEM_CALLSTACK'
IMPORTING
et_callstack = ta_callstack.
LOOP AT ta_callstack INTO wa_callstack.
WRITE: / wa_callstack-progname,
wa_callstack-eventtype,
wa_callstack-eventname.
ENDLOOP.
ENDFORM. "call_routine_2
The output will look like this:
ZZ_SYSTEM_CALLSTACK FORM CALL_ROUTINE_2
ZZ_SYSTEM_CALLSTACK FORM CALL_ROUTINE_1
ZZ_SYSTEM_CALLSTACK EVENT START-OF-SELECTION
