Cause: The form tried to invoke a user exit that does not exist. This could be caused by one of the following:
1. You are using the wrong version of Forms Runtime.
2. There could be an error in the form.
Action: If you are using the wrong version of Forms Runtime, determine which version contains the user exit, and use that version to run the form. If there is an error in the form, the designer should correct the call to the user exit.
