Selection Screen Error

Former Member — Wed, 27 Dec 2006 07:52:50 GMT

Hi,

I am validating selection screen inputs. If i enter wrong value. i am showing an error. It displays error message properly but it takes screen to other blank screen.

How can i show error message on same selection screen?

Code:

start-of-selection.

IF pa_to < pa_from.

MESSAGE e274(gs).

ENDIF.

Thanks in advance,

The same code should be written in At Selection-screen event, But not in Start of selection.

Cheers.

The Problem is occuring because you are doing the validation on the Start of Slection event....Usually the validations must be done on At Selection screen event....since you want to remain on the same screen write the same code under At Selection Screen event and your problme is resolved.

Hope This Helps

hi,

This will work

AT SELECTION-SCREEN.

IF pa_to < pa_from.

MESSAGE e274(gs).

ENDIF.

for E type of messages.

Selection screen processing terminates, and the selection screen is redisplayed. The screen fields specified through the additions to the AT SELECTION-SCREEN statement are ready for input. The user must enter a new value. The system then restarts the selection screen processing using the new values. You cannot use error messages with the ON HELP-REQUEST , ON VALUE-REQUEST and ON EXIT additions. Instead, a runtime error occurs.
