dataflow refresh failing with "invalid credential" when merging 2 tables



I have a dataflow with 2 Tables

TableA contains the "Table A" object from an xls source file stored in the sharepoint site linked to our service environment

TableB contains the "Table B" object from the same xls source file


When I do a service refresh (manual or scheduled) with the above it completes succesfully.


Then I try to add to TableA 4 fields from TableB with a merge query function.

While I am in the dataflow editor, it works. I can see the additional values.

When I do a service refresh (manual or scheduled), if fails on the TableA with the error message 

Error: The credentials provided for the PowerBI source are invalid. (Source at PowerBIInternal.).


I looked at the credential, they are OAuth2, I tried all the Privacy level settings but nothing solved the issue.


Thank you for your help

check the 'awareness' section

yes this is due to this linked entitiy issue in the service environment. I worked around it be duplicating the TableB, not enabling load on this duplicate item and doing the merge with this duplicate item.
