Warning message produces short dump in user exit
I have a user exit for transaction VA02, on which a warning message is displayed. It works fine when modifying the orders, but when I try to delete one, it produces a short dump with the following description:
+The program attempted to issue a " " message during "Exit Command" processing.
This is an illegal operation.
The program was terminated.+
Is there any way to bypass this issue?
I've tried other types of messages and error also produces a short dump, while success and information work fine...
Thank you all very much.
