Answer 1

Hi,
For this requirement we need to use UPDATE... SET... WHERE.... statement.
plz have alook on this example :
UPDATE zo9_user_status
                SET  sub_date = sy-datum
                     sub_time = sy-uzeit
                     status = g_wa_outtab-status
                WHERE  representative = g_wa_outtab-representative AND
                       selection_id = g_wa_outtab-selection_id AND
                       sub_date = g_wa_outtab-sub_date AND
                       sub_time = g_wa_outtab-sub_time AND
                       superior = g_wa_outtab-superior.
        IF sy-subrc EQ 0.
          COMMIT WORK.
          l_error = 'X1'.
        ELSE.
          l_error = 'X2'.
          CLEAR l_error.
          ROLLBACK WORK.
        ENDIF.
In your case we can have
UPDATE zo9_user_status
                SET  zdate = sy-datum
                        ztime = sy-uzeit
              WHERE werks = g_wa_outtab-werks AND
                       sub_date = g_wa_outtab-zdate AND
                       sub_time = g_wa_outtab-ztime .
        IF sy-subrc EQ 0.
          COMMIT WORK.
          l_error = 'X1'.
        ELSE.
          l_error = 'X2'.
          CLEAR l_error.
          ROLLBACK WORK.
        ENDIF.
This will surely solve your problem.
hope this helps.
thanx,
