Problem in dynamic selection screen

Former Member — Thu, 20 Mar 2008 06:29:07 GMT

Hi,

I have a parameter P1 on the selection screen.When i am entering some value in that field some more field should be displayed below it on the selection screen.For ex. when i am entering 1 P2,P3,P4 should come.Whe i am entering 2 P3,P4,P5 should come.I also need a validation that the user cannot execute without pressing enter after entering the value in P1.

Hi Mukesh,

I can suggest one solution. Instead of taking selection screen directly take a screen generated thru screen painter and call it in place of selection screen. Here u can get the remaining paramters displayed by setting the properties in the PAI block.

awrd points if useful

Hi,

Check this out.

SELECTION-SCREEN : BEGIN OF BLOCK blk2 WITH FRAME TITLE text-002.

PARAMETER : p1 type < > USER-COMMAND change,

PARAMETER : p2 type < > MODIF ID m3,

p3 type < > MODIF ID m3,

p4 type < > MODIF ID m3,

p5 type < > MODIF ID m4,

p6 type < > MODIF ID m4.

SELECTION-SCREEN:END OF BLOCK blk2.

AT SELECTION-SCREEN OUTPUT.

check p1 is not initial.

LOOP AT SCREEN.

if p1 = '1'.

IF screen-group1 = 'M3'.

screen-INPUT = 1.

ELSE.

screen-INPUT = 0.

screen-invisible = 1.

ENDIF.

endif.

if p1 = '2'.

IF screen-group1 = 'M4'.

screen-INPUT = 1.

ELSE.

screen-INPUT = 0.

screen-invisible = 1.

ENDIF.

endif.

MODIFY SCREEN.

ENDLOOP.

For validation for pressing enter, check sy-ucomm.

Reward if helpful.

Hi,

Please declare all the P2,P3.P4.P5 in the select-options.Make all the all the fields except P1 as screen-visible = '0'.

Now if user enter anything put the corresponding logic in AT selection-screen output saying if P1 = 1 then make LOOP at SCREEN with name as P2,P3,p5 and make VISIBLE = '1'.

Suppose user directly executes then code at selection screen if P1 = 1 the LOOP at screen for P2 and check if it si still invisible if so throw message saying "Please enter after making entry in P1 field".
