Hi @Anonymous ,

There was an error when processing the data in the dataset.
[Unable to combine data]: Table references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

• One reason for this problem is privacy setting which don’t allow multiple sources in single query. Check privacy settings in your report file and every data source used.

  In report file settings you must ignore Privacy settings.

• This problem can be solved by moving your query to Data Flow and using Data Flow as a source in report.

  So create new Data Flow in your workspace and copy your original query there.

  And now for the important part. If you try to refresh your data flow you will end up with another combination error message. You have to change Data Flow Privacy Level as described in picture.

Hey @Anonymous ,

When you go to "Section1/Query1/Expanded Table Column1 " do you see which step it is referring to?  And, is that step a data combination of something local or a non-SQL data source?  Also, is your gateway up to date and is your Power BI Desktop file up to date?  IF they are of sync quite a bit you can get interesting issues similar to this as well.

There is a invoke custom function which is inserting the data in on perime databases

Hey @Anonymous ,

In addition to what @v-rongtiep-msft stated, I am wondering, is your function taking a result FROM the query and then inserting data?
