HI PRASHANT,

Check this code.

Got to screen , press F1 over that element(parameter or select option)

field of that partcular element, now go to technoical information there u'll

find screen field name of that component. This way find screen field name of all components on the selction screen which u want to hide. and set input and invisble prpoerty as required as shown in the code below, modify screen.

REPORT z1 .

DATA gv_budat TYPE erdk-budat.

PARAMETERS p_budat LIKE gv_budat.

SELECT-OPTIONS so_budat FOR gv_budat.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF screen-name = 'SO_BUDAT-LOW'

OR screen-name = 'SO_BUDAT-HIGH'

OR screen-name = '%_SO_BUDAT_%_APP_%-TEXT'

OR screen-name = '%_SO_BUDAT_%_APP_%-VALU_PUSH'

OR screen-name = '%_P_BUDAT_%_APP_%-TEXT'

OR screen-name = 'P_BUDAT'.

screen-input = '0'.

screen-invisible = '1'.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

This is working.

Pls reward points to all answers.

Hello prashant patil,

We can desable the select-option field using the statement SCREEN-INPUT = 0.

Just have a look on the following code :

select-options: s_werks for marc-werks modif id g.

at selection-screen output.

loop at screen.

if screen-group1 eq 'G'.

screen-input = 0.

refresh s_werks.

endif.

modify screen.

endloop.

here i'm selecting the select-option s_werks and i initialize modif id value for s_werks as G. The condition if that screen-group equals to G then the select-option s_werks is desables.

For more information on MODIF ID go through the following info.:

To modify the appearance of an input field on the selection screen, you must assign the parameter to a modification group as follows:

PARAMETERS p ...... MODIF ID key ......

The name of modification group key should be a three-character variable name without quotation marks. The MODIF ID addition always assigns key to the screen-group1 column of internal table screen. Parameters assigned to a modification group can be processed as an entire group with the LOOP AT SCREEN and MODIFY SCREEN statements during the AT SELECTION-SCREEN OUTPUT event.

For more information on modification groups and internal table screen, see Modifying the Screen.

REPORT demo_sel_screen_param_modif.

PARAMETERS: test1(10) TYPE c MODIF ID sc1,

test2(10) TYPE c MODIF ID sc2,

test3(10) TYPE c MODIF ID sc1,

test4(10) TYPE c 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.

The parameters test1 and test3are assigned to the modification group sc1, while test2 and test4 are assigned to group sc2. During the AT SELECTION-SCREEN OUTPUT event, the INTENSIFIED field of internal table screen is set to 1 or 0, depending on the contents of the group1 field.

Reward me if it is useful to you.
