Message: 'Abort Transaction' should be set to 'Yes' for 'AllException' error handler at screen flow level
Cause: You have an Error Handler in a Screen Flow to catch general exceptions and the Abort Transaction property is set to 'No'.
Recommendation: You should change the Abort Transaction property to 'Yes' because, since the Error Handler is catching all exceptions, the current database transactions should be aborted to avoid committing inconsistent data.
