Helper IVWeird error with refreshing combined tables
I have a rather strange issue with one of my combined tables when refreshing the dataset.
The first time I'm refreshing the data (usually in the morning) I am getting an access / references error that blocks the other queries.
If I go into the editor and refresh the table there, it loads fine.
Same if I close the BI and try again a bit later.
The columns in the tables I'm combining have the same names, and the formula in the merged table is just a simple
= Table.Combine({import_A, import_B, import_C})
If I redo the merging the formula in the new table looks exactly the same too, and gives the same weird error.
The source tables themselves are loaded from a mysql database, but that one is accessible and properly loads the other tables, so I don't see the issue there.
I managed to solve the issue by joining the tables on import in the power bi query SQL option with UNION ALL.
I solved the problem by pulling the columns with sql code in the power bi query and using UNION ALL to join them at the time of import, so power bi only has one table to deal with.

I was able to figure it out. It looks like I had to set the privacy level to `Organizational` on both the Dekstop version and the service level.
