I want to export a TSV file to deliver to an ETL service but the XLSReport seems to have it against me. I´m really not sure what this error is going to tell me. I have no constraints, only one reference on Inner Join. I have double checked at the app store and all the code should be downloaded. If someone can help me decode this stack trace that would be great. Regards, Derk-Jan An error has occurred while handling the request.
