Paginated Reports in App - Could not connect to the data source

[dennisnxl]

Hi

I have a paginated report which is built in Power BI Report Builder and it uses shared Power BI dataset with RLS (Premium workspace).

I published the report as an app and I can use it without any problems, but oher users (e.g. external) with access to the App get the following error:

Could not connect to the data source.

There was an error communicating with Analysis Services. Please verify that the data source is available and your credentials are correct. The connection either timed out or was lost.

I already gave app users Build permission on the dataset as suggested at  Error when accessing paginated reports published to an app - "Could not connect to data source" 

Any ideas how to fix that?

Btw. I don't want to add all users to the workspace - just to the app.

Edit: The report works without RLS, so as workaround I will build the security around separate datasets.

Any luck in solving this issue? Have you find a resolution already?

In this case I simply removed row level security and created a separate dataset for each "role".

Back then it was a classic workspace, but since the new workspace experience is available (which gives more control over roles) it is no longer an issue.

More information about differences between classic and new:

Hi @dennisnxl,

Thank you for your response.

Yesterday I did some further testing and I discovered that in our current situation it was caused due to the combination of having an group assignment at role level ("Security") and an individual assignment at permission level ("Manage permissions") regarding the given dataset. It is still under investigation; it might result into a ticket to Microsoft.

Hi @dennisnxl ,

Is your data source "Analysis Service"? If it is, do you map user names? If not, please refer to this document to map user names.
