Re: At Selection-screen query

Hi Gita,

You can store the value of SY-SUBRC in a FLAG variable and then display the message at the END-OF-SELECTION event as the SY-SUBRC stores the state of last executed statement and the END-OF-SELECTION statement would always trigger it to 0.

for e.g.

AT SELECTION-SCREEN.
SELECT COUNT(*) FROM  dd02l INTO v_cnt WHERE TABNAME = p_tabnam.
FLAG = SY-SUBRC.

END-OF-SELECTION.
   IF FLAG EQ 0.
     MESSAGE 'Valid Table Name ' TYPE 'S'.
   ELSE.
     MESSAGE 'Invalid Table Name' TYPE 'S' DISPLAY LIKE 'E'.
   ENDIF.
