Module Function not being called by the planning function

Question

Hi all,
I am having a problem with the MF assigned to the planning function of my planning level. It's not being called when executing the layout using Planning Folder. This action is suppose to be taken when saving the entries of the layout (I have made the proper setting in planning folder)
When I execute the planning folder and manually introduce data in the layout and save, the MF is not executed but data is loaded in the infocube anyway. I have put a breakpoint in the MF but never stops, as never has been called.
Please, could anyway let me know his comments?
Best Regards!

Answer 1

Hi Jose,
There could be two reasons why the FM might not work.
1. The level selections for which the FM runs and the Layout gets executed might different and the FM is not getting the Requisite Data set to read data from .
The solution could be check the level selections and execute the FM .Also after you save the Data ,please do an F9 to check the display message.Chekc if oyu Function module is reading any data set at all(ifit says 0 read ,0 changed statement i mean).
2. The second reason could be that the FM is not initialised at all.To initialise the FM you need to write an initialisation FM and place it in the INIT part of the Exit function.This creates dummy records if your data set is initially empty which is the case here.Here is a sample code you might get reference from .
Create one dummy combination
If we don't do this, the upload won't work since the second function
will not be executed at all in case no transaction data exists so far.
The combination must be a subset of the planning level!
" >>> BEGIN INSERT
  IF l_count = 1.
    EXIT.
  ELSE.
    CLEAR ls_chas.
    CLEAR: ls_chasel.
    LOOP AT ito_chasel INTO ls_chasel.
      CLEAR: ls_charng.
      READ TABLE ls_chasel-t_charng INTO ls_charng INDEX 1.
      IF sy-subrc = 0.
        ASSIGN COMPONENT ls_chasel-chanm OF STRUCTURE ls_chas TO <f>.
        IF sy-subrc = 0.
          <f> = ls_charng-low.
        ENDIF.
      ENDIF.
      CLEAR: ls_chasel.
    ENDLOOP.
  ENDIF.
  " <<< END INSERT
  COLLECT ls_chas INTO lto_chas.
  eto_chas = lto_chas.
ENDFUNCTION.
Hope this helps.
