Hi,

If you have to do any modification in Screen table you will do it in At selection-screen output.

please see the code below.

AT SELECTION-SCREEN OUTPUT.

*disable the date range selection screen option

IF rb_today EQ 'X' OR

rb_cntm EQ 'X' OR

rb_cntyr EQ 'X' OR

rb_past EQ 'X' OR

rb_all EQ 'X' OR

rb_fut EQ 'X'.

LOOP AT SCREEN.

IF screen-name EQ 'S_D_RAN-LOW' .

AND if SCREEN-NAME eq 'S_D_RAN-HIGH'.

screen-input = '0'.

MODIFY SCREEN.

EXIT.

ENDIF.

ENDLOOP.

LOOP AT SCREEN.

Hi,

Generally, if we wnat to modify the selection-screen layout, then we use AT SELECTION-SCREEN OUTPUT statement.

e.g. if u have 4 fields on your selection screen and I want to make 1 field of them as non-editable with a default value of '10'.

then I will write the code as :

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF SCREEN-NAME = 'FIELD1'.

SCREEN-INPUT = 0.

SCREEN-OUTPUT = 1.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

Not only this u can hide a field, make a field mandatory and do many more things with the fields on the selection-screen using the AT SELECTION-SCREEN OUTPUT event. This event actually is a PBO event for Selection screen.

Himanshu

Hi,

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.

Ex.

REPORT DEMO.

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.

Bhaskar
