Cost assignment check in IT 0015

Question

Hi all,
I have to do additional cost assignment check in IT 0015. There are only few allowed combinations of fund, fund area and WBS element. Allowed combinations are stored in table FMBASOBJNR.
After click on "Maintain cost assignment" is called FM RP_TIME_COBL_002, but I haven't found any user exit where I could put my code.
The other way how to check it, is to do it in user exit EXIT_SAPFP50M_002, but tables ASSHR and ASSOB are empty at the moment when check is called and I don't know where cost assignment is stored.

It is called twice.. once when you click on  'Maintain cost assignment' & again when you hit on SAVE.... you have to clear the values in the cost assignment .. something like the following should work for you..
method IF_EX_HRPAD00INFTY~AFTER_INPUT .
  data w_flg.
   import w_flg to w_flg from memory id 'ZTST'.
  if w_flg eq space and not ipref is initial.
* do your Cost Assgnment validations & error out
     clear ipref.
*  message e016(rp) with 'test'.
  w_flg = 'X'.
  export w_flg from w_flg to memory id 'ZTST'.
  endif.
endmethod.
