@battk Been there; done that. The writeResponse status is a 'isIsSuccess", but the change is not being made. I would settle for just being able to delete the custom record and have my web services process rebuild it (with a correct external id), but I am also having trouble when I try to delete the record through SuiteTalk. I have been looking for an example of this delete process (I have never used SuiteTalk to delete a custom record) but have not found one yet. Any ideas as to where I can look?
