Answer 1

i did this :
wa-fieldname = 'Month '.
wa-seltext_m = 'nMonth '.
APPEND wa TO fieldcatalog.
CLEAR wa.
* "2
wa-fieldname = 'Year '.
wa-seltext_m = 'nYear'.
APPEND wa TO fieldcatalog.
CLEAR wa.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    IT_FIELDCAT = fieldcatalog
  TABLES
    T_OUTTAB    = GetData.
IF SY-SUBRC <> 0.
* Implement suitable error handling here
ENDIF.
the result is empty.
it returns the columns but the result is empty.
please advise.
thanks,
