Hi Sunil,

Instead of making a selection screen like this the best way is do this validaion in AT SELECTION SCREEN.

There you can check for these conditions and it is only the best way to do this.

Agreed - this is best done in the "at selection-screen" event... one thing to be careful of is that since you appear to be using select-options for each criterion, you need to code you validation to check the body of the range, not just the screen elements i.e.

if s_bukrs[] is initial.
  set cursor field 'S_BUKRS-LOW'.
  message e398(00) with 'Company Code must be provided'
    space space space.
endif.

Hi Guys,

iam asking how to write code for looping the screen.

i.e., we must give value either 'A' or 'D' ('A' or 'D' is Mandatory)

if we give any value for 'A' then 'B', 'C' should be mandatory( if 'A' is populated)

if we give any value for 'D' then 'E', 'F' should be mandatory( if 'D' is populated)

I think this condition will be done on AT Selection-Screen OUTPUT.

Hi Sunil

This validation is done in AT SELECTION-SCREEN event.

Your Code:

AT SELECTION-SCREEN.

IF A[] IS INITIAL AND D[] IS INITIAL.

Message 'Error' TYPE e. " Sunil replace this by your message class.

ENDIF.

IF NOT A[] IS INITIAL.

IF B[] IS INITIAL OR C[] IS INITIAL.

Message 'Error' TYPE e. " Sunil replace this by your message class.

ENDIF.

IF NOT D[] IS INITIAL.

IF E[] IS INITIAL OR F[] IS INITIAL.

Message 'Error' TYPE e. " Sunil replace this by your message class.

ENDIF.
