how to execute function module dynamically

Former Member — Fri, 20 Mar 2009 15:01:25 GMT

Hi, I have list of function modules in internal table and I have to execute function modules one after the other. Could anyone please advice how can we execute FM dynamically/how to execute FM one by one.

Thanks in advance.

See ABAP online docu for the CALL FUNCTION statement, the name can be passed dynamically inside a loop at your internal table.

All function modules should have the same interface, otherwise things would become very complex or ugly.

check below code.

REPORT zdemo.

DATA: BEGIN OF itab OCCURS 0,

name TYPE string,

END OF itab,

wa LIKE itab.

wa-name = 'GUI_RUN'. <-- FM1 name

APPEND wa TO itab.

wa-name = 'GUI_DOWNLOAD'. <-- FM2 name

APPEND wa TO itab.

LOOP AT itab INTO wa.

CASE wa-name.

WHEN 'GUI_RUN'. <-- Call FM1

CALL FUNCTION 'GUI_RUN'

EXPORTING

command = 'cmd'.

WHEN 'GUI_DOWNLOAD'. <-- Call FM2

~~-code~~-

ENDCASE.

ENDLOOP.

Use BDC ( call transaction).
