Advocate IIError: [Unable to combine data] Sorry there was an error while buffering the data for Section1
Hi,
I am receiving the followng error when trying to refresh my data on dataflow. This works fine in PBI Desktop and PBI services. It even validates without errors in dataflow, but when I refresh is when I receive this error. Full error message below:

Also, not sure why it is looking for the 'EESAPMaster.csv' file. 'EESAPMaster is the name of the query, so maybe it is stored as a .csv file?
Thank you!

Hi Kevin,
I was having the same issue. It appears to be resolved by ticking the option "Allow combining data from multiple sources" in the Project Options within the dataflow editor.

Hi there
It would indicate that from your dataflow it is looking for the underlying CSV output from your query?
