selection screen help

Former Member — Wed, 05 Nov 2008 08:01:41 GMT

hello experts ,

i am facing a problem in the selection screen.

my object is to use two block in a selection screen in which i have two parameters and a check box in each block. And i have kept a parameter as mandatory in a block. Here the problem is that i have kept the parameter as mandatory so the 'at selection screen output' event is not getting triggered without entering any values to parameter.

this is my coding.

SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME title TEXT-001.

SELECT-OPTIONS : S_GSBER FOR TGSB-GSBER OBLIGATORY MODIF ID M1,

S_AUGDT FOR BSAK-AUGDT MODIF ID M1.

PARAMETER : P_BUKRS TYPE T001-BUKRS MODIF ID M1,

TEST TYPE C AS CHECKBOX USER-COMMAND Z1 DEFAULT 'X' MODIF ID M1.

SELECTION-SCREEN END OF BLOCK B1.

SELECTION-SCREEN BEGIN OF BLOCK B2 WITH FRAME TITLE TEXT-002.

PARAMETER : CTP TYPE C AS CHECKBOX USER-COMMAND Z1 DEFAULT 'X' MODIF ID M2.

SELECT-OPTIONS : S_DD FOR SY-DATUM MODIF ID M2,

S_PD FOR SY-DATUM MODIF ID M2.

SELECTION-SCREEN END OF BLOCK B2.

AT SELECTION-SCREEN OUTPUT.

IF TEST = 'X' AND CTP = 'X'.

LOOP AT SCREEN.

IF SCREEN-GROUP1 = 'M2'.

SCREEN-INPUT = '0'.

MODIFY SCREEN.

ENDIF.

Here when i uncheck the 'test' checkbox it is showing error to 'fill all the required fields'. so how can i get rid of it.

in this case you have to remove the OBLIGATORY statement and check in the AT-SELECTION SCREEN OUTPUT if the field is filled or not. something like:

IF field IS INITIAL.
MESSAGE ...
ENDIF.

Hi,

I modified ur code...and it is working now...


SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.

SELECT-OPTIONS : s_gsber FOR tgsb-gsber MODIF ID m1,        "remove OBLIGATORY
s_augdt FOR bsak-augdt MODIF ID m1.

PARAMETER : p_bukrs TYPE t001-bukrs MODIF ID m1,
test TYPE c AS CHECKBOX USER-COMMAND z1 DEFAULT 'X' MODIF ID m1.

SELECTION-SCREEN END OF BLOCK b1.

SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE text-002.

PARAMETER : ctp TYPE c AS CHECKBOX USER-COMMAND z1 DEFAULT 'X' MODIF ID m2.

SELECT-OPTIONS : s_dd FOR sy-datum MODIF ID m2,
s_pd FOR sy-datum MODIF ID m2.

SELECTION-SCREEN END OF BLOCK b2.

AT SELECTION-SCREEN ON s_gsber.           "ADD this...
  IF sy-ucomm NE 'Z1' AND s_gsber IS INITIAL.
    MESSAGE 'Enter value' TYPE 'E'.
  ENDIF.


AT SELECTION-SCREEN OUTPUT.
  IF test = 'X' AND ctp = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'M2'.
        screen-input = '0'.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ENDIF.

Hi Arun,

For my understanding I think you should remove the Obligatory from the chcek box and put that condition in the event AT SELECTION-SCREEN OUTPUT. This way your problem will solve.

Thanks,
