I loaded two Execel files to Sharepoint and brought them into Dataflows in app.powerbi.com. I did a merge (not as a new table) on one of my queries and the refresh failed. I get the following error message:
Error: An internal error occurred... RootActivityId = e600e75b-60b7-48bf-b451-3a7962d0b852.Param1 = Information about a data source is required. Request ID:
I changed the privacy settings to each option (Organizational, Public, Private, None) and it still continues to fail during refresh. However, when I do a merge as a new table, the refresh works. Why is it that when I try to do merge on an exisiting table, it fails but works when I merge into a new table?
Thanks!
