How to cancel screen processing having error messages in field input ?

Hello all..

I have a screen with fields captions attached to standards Search help. If user input an invalid value, standard error message appear.

In this moment I wish my button CANCEL go out and Ignore error, but it doesnt happen. Screen remains active and error message continues appearing. Event CANCEL dont work in this case.

In my user-command module, command CANCEL do the following:

- ask user if want to exit without saving.

- if yes, perform LEAVE PROGRAM

thanks by advance.
