I am trying to use the GET PARAMETER ID, for various transactions. So, the code that I have written is:
CALL TRANSACTION 'IA05'. GET PARAMETER ID 'PLN' FIELD gv_plnnr. GET PARAMETER ID 'PAL' FIELD gv_plnal. CALL TRANSACTION 'IA06'. GET PARAMETER ID 'PLN' FIELD gv_plnnr_r. GET PARAMETER ID 'PAL' FIELD gv_plnal_r.
In both the transactions the values of the ID PLN (Task List Group - plnnr) are fetched, but the values for ID PAL (Group counter - plnal) are not fetched. I checked and in both of them the parameter id for the field PLNAL is PAL.
The sy-subrc after the get paramter IDs is always 0.
Can anyone tell me why are the data not fetched?
