problem with validation!!!!!!!

Former Member — Tue, 22 Jan 2008 13:34:20 GMT

Hi All,

I have got a matnr select option in screen. i have to validate this for initial and whether entered value exist in database. If condition fails i have to show the selection screen with message. But what happens is that

after displaying the messaage it executes the statements in start of selection event.

I am doing validation in atselection screen event. I then added an exit statement if the condition fails, But exit seems to exit from the particular even only and not from the application. How can i achieve this? please reply.......

use type E when displaying the message, this will process the selection screen (PBO/PAI) as long as the error has not been corrected by the user.

replace EXIT statement with SUBMIT statement.


"Message statement
SUBMIT (sy-repid) VIA SELECTION-SCREEN.

Hi,

You can do as below :

at selection-screen.

Check for the condition.

if it is failed,

GIve the message as below :

If sy-subrc NE 0.

Message 'Not a valid Material Number' Type 'E'.

endif.

This will terminate the program and shows the selection screen again for input.

Thanks,

Sriram Ponna.

Hi,

Instead of EXIT, Use LEAVE LIST-PROCESSING.

This will solve your problem.

Hi,

Try doing the validation in INITIALIZATION event.

If sy-subrc NE 0.

exit.

endif.
