Power Query Formula.Firewall Error in Desktop
I’m seeing a 'Formula.Firewall' error when I try to refresh my query. The message says about combining data sources, even though both sources are actually from the same file. This just started happen...
Mohit_009 Try the below approaches to resolve the issue.
1. Go to File -> Options and settings -> Data source settings, make sure both sources have the same privacy level and then refresh the query.2. You can enable ignore privacy levels option to bypass the privacy error.
