Dear Jim,
I'd like to comment the usage of ANST for query or other abap code deneration utilities like transaction PU12. I those cases, the issue should be reproduced from the beggining. that is. running the query won't probably be enough, but you have also to create or generare the query a part of the steps to reproduce the issue.
Reason: If there is a correction note for the query functionality, the correction instructions will always be done in the generation part of the query and not in the query itself.
Regards,
Carlos.
