A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Hi Mia - Thank you for your reply. The problem seems to be isolated to one workbook and clearing the cache did not help. I have now copied the various sheets into a new workbook and re-made the power queries. This seems to work and the alert is now gone. My take is that somehow the Data Model in this particular workbook got corrupted and there was no obvious way to fix this. Another hint in this direction is that the Workbook Queries & Connections lists a number of connections that are not real and they cannot be removed or refreshed. In the new workbook, I only see the real connctions I have created and they behave normally. Again, the problem appeared when version 16.68 was installed.
