Hi,

You can use the LOOP AT SCREEN statment .... In the event AT SELETION SCREEN OUTPUT we use this LOOP AT SCREEN and ENDLOOP statments

PARAMETERS: TEST1(10) MODIF ID SC1,
            TEST2(10) MODIF ID SC2,
            TEST3(10) MODIF ID SC1,
            TEST4(10) MODIF ID SC2.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.
  IF SCREEN-GROUP1 = 'SC1'.
    SCREEN-INTENSIFIED = '1'.
    MODIFY SCREEN.
    CONTINUE.
  ENDIF.
  IF SCREEN-GROUP1 = 'SC2'.
    SCREEN-INTENSIFIED = '0'.
    MODIFY SCREEN.
  ENDIF.
ENDLOOP.

Hello,

Yes, you can use LOOP AT SCREEN...ENDLOOP in the SELECTION SCREEN.

I guess you are looking for some modification on the screen interms of either hiding elements or enabling input etc. on the screen depending on some conditions. All these are modification to the SCREEN and happen at the event AT SELECTION-SCREEN OUTPUT.

Following is one sample code showing how to do this. Here depending on the MODIFICATION Group IDs, fields are made input enabled and disabled.

PARAMETERS: CUSTNAME(10) MODIF ID ID1,
            CUSTADDR(10) MODIF ID ID1,
            VENDNAME(10) MODIF ID ID2,
            VENDADDR(10) MODIF ID ID2.

 
AT SELECTION-SCREEN OUTPUT. 
LOOP AT SCREEN.
  IF SCREEN-GROUP1 = 'ID1'.
    SCREEN-INPUT = '1'.
    MODIFY SCREEN.
    CONTINUE.
  ENDIF.
  IF SCREEN-GROUP1 = 'ID2'.
    SCREEN-INPUT = '0'.
    MODIFY SCREEN.
  ENDIF.
ENDLOOP.

Hope this helps.
