When Business Central reports are generated in Microsoft Cloud, the rendering is done via a ForNAV service endpoint. The endpoint receives the report layout and the data needed to produce the finished report. Normally, the data for the report is not stored anywhere. When the report is created, the data is gone.
In a debugging scenario, it can be helpful to store the report data and corresponding layout so that the rendering can be reproduced in a controlled environment. Therefore, there is a field in the ForNAV setup page where you can tell the service endpoint to keep the data for debugging purpose. The field is called Endpoint Settings. It holds a text string that is sent to the endpoint when the report is created.
To enable debugging mode, type the value debug in the Endpoint Settings field. When the next report is run, the report information is stored and ForNAV support can help analyze the result.
