Formula.Firewall: Query '_VP' (step 'Changed Type2') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

HI @Analitika,

Yes, I saw your notifications before I replied. I'd like to suggest you take a look at the blog to confirm if these operations that the blog mentioned also include in your report.

Where are these messages display? Desktop or service side?

If you are work on the desktop side, did you update your power bi desktop recently? (desktop update may include some new release on the query editors or notifications)

If you are working on power bi services side and these reports work normally in the past, they can also be caused by internal or backend processing of power bi service.

Notice: these notifications may not be displayed immediately when you add them to your query steps.

HI @Analitika,

In fact, this notice does not mean the bug, it works as expected.
It means power bi increase the security levels of 'data privacy' so that power bi will check all the queries and their steps to confirm if your queries existed similar operations.

You can take a look at the following link to change the data privacy settings to fix this issue.
