Hi,

Check the validation in AT SELECTION event after E type messages,

For Screen programming try with CHAIN ENDCHAIN...

Thanks

Gourav.

Define a BLOCK in SELECTION-SCREEN and use AT SELECTION-SCREEN ON BLOCK so every field define in the BLOCK will be available for input when an error is raised. Usually group parameters which are used in a common check like a SELECT using multiple parameters in the WHERE criteria.

SELECTION-SCREEN BEGIN OF BLOCK block.
    SELECT-OPTIONS: g_struct FOR LXE_OBJCTS-OBJECT_NAM NO INTERVALS.
    SELECT-OPTIONS: g_others ...
SELECTION-SCREEN END OF BLOCK block. 
AT SELECTION-SCREEN ON BLOCK block.
    PERFORM validation_struc.
    PERFORM validation_others...

Regards,

Raymond

Dear Kiran,

Try the event AT SELECTION-SCREEN ON OUTPUT.

LOOP AT SCREEN.

IF SCREEN-NAME = " ".

SCREEN-ACTIVE = 'X'.

ENDIF.

ENDLOOP.

hi Raymond,

i have two select option fields and i have also designed other normal screen fields like input fields, check boxes, radio buttons in module pool,.

when i enter wrong value in selectoption field , all other screen fields are disabled,

instead of that i need to show only error message and all other screen fields must be enabled.

Hello Kiran,

Try to use Chain and Endchain statement to enable remaining fields for input. Hope this will solve your problem.

Try to display error message in a popup screen using following statement

MESSAGE 'text' TYPE 'I' DISPLAY LIKE 'E'.

write the following statement after above statement.

LEAVE TO SCREEN sy-dynnr.

Hello Kiran,

Have you followed any of my previous suggestion. If yes, then which one you followed?

Give a try with other one also.

I tried both of them , but i am still facing the problem with the tab strip,

Hello Kiran,

In the second option try to modify the statement Leave... , use the main screen number in which your tabstrip is present instead of using sy-dynnr. let me know how it goes.

One more question, without my suggested code, are you able to access other tabs when cursor is in the select option field?

I have tried the option with call screen statement it works ,

but I got one more problem , when i am switching repeatedly between two tabs my program

goes to dump saying that

'No further list processing possible , you requested too many consecutive nested call screens .at present maximum number of permitted nested screen levels is restricted to 50'.

then it shows my code what i have written in validations,,...

FORM VALIDATION_STRUC .

DATA: lv_tabname TYPE dd02l-tabname.

CASE OK_CODE.

WHEN 'TRANSL'.

if g_struct-low IS INITIAL.
   MESSAGE ID g_mid TYPE 'E' NUMBER '001'.
ELSE.
SELECT SINGLE tabname INTO lv_tabname
                       FROM dd02l WHERE tabname = g_struct-low.
         IF sy-subrc <> 0.
         MESSAGE ID g_mid TYPE 'E' NUMBER '000'.
        ENDIF.

ENDIF.
WHEN OTHERS.
call SCREEN 110.
ENDCASE.
ENDFORM.

Hello Kiran,

I believe this is due to the following code.

" WHEN OTHERS.

call SCREEN 110. "

in the validation which is called every tab in the tabstrip control repeatedly and every Ok_code other than TRANSL.

Try to remove the above code and give a try.

Hello Kiran,

yes it is because of this code,

you can replace the call screen with leave to screen xxx.

" WHEN OTHERS.

leave to screen 110.

for your validations: why dont you try CHAIN ENDCAHIN instead of doing all these.
