Hi,

Use a BLOCK and then validate in

AT SELECTION SCREEN ON BLOCK b0.

Define both the blocks in a third block and use the validation on that block.

I guess u can have upto 5 nested blocks. SAP has provided blocks only for the above requirment scenarios..

Hi ,

I cannot use blocks for this because the fields to be validated are not placed serially...there other fields in between which remain open if i use the validation on the block .

Thnx nd regards,

use information message instead of error message

[Laxmana_Appana_]

Hi,

Define screen groups on related fields and do the validations.

sample code :

REPORT demo_at_selection_screen_pbo.

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.

Hi Srestha,

try this.

Define a S message and then trigger LEAVE LIST-PROCESSING to return back to the selection screen.

MESSAGE S999(ZM) with 'ERROR TESTING'.

LEAVE LIST-PROCESSING.

My 2 cents on this.. Best is to rearrange the selection fields and use the validation at blocks.

use only AT SELECTION_SCREEN instead of AT SELECTION-SCREEN ON FIELD and try

If you define all the fields in a single block than it would make all the fields as enabled.

Hi,

I think as mentioned above by Chandrasekhar ,

in ur case best option is to simply use AT SELECTION-SCREEN.

AT SELECTION-SCREEN.
  IF CARRID-LOW IS INITIAL 
    OR CITY_FR IS INITIAL 
    OR CITY_TO IS INITIAL. 
    MESSAGE E000(HB). 
  ENDIF.

You can verywell display a error message...

Hi,

One solution is:

Set a flag if an error occurs at selection-screen validation.

And, AT SELECTION-SCREEN OUTPUT, use this flag and loop at screen to set the other field enabled for input...

Hope you understood....

Hello,

Can you paste your selection-screen and the conditions on which you want to raise error?
