Power BI - SSAS on prem (could not access model schema)

I have recently joined a new organisation and am building a cube/PBI report.

My report utilises an on-premise SSAS cube (in live connect mode) and have deployed it the Power BI service, using the BI gateway I have created a connection to the cube using credentials that have admin access to the cube. I have linked this up to the reports dataset and can run the report through the PBI service.


The issue I am having is that I have shared it with an end user (for approval), giving them access to the report and read only access to the dataset, however they receive the error "could not access model schema".


My concern is that this is could b due to the user not having access to the cube itself, my reason for not giving permissions to the cube to the user is intentional, as whilst I am happy for them to see the report sitting on top of the cube, I don't want them being able to connect to the cube through Excel/PBI.


Any suggestions more than welcome, either identifying if there is possibly another issue at hand or how I can impersonate credentials when connecting as opposed to giving blanket access to the users using the report.


Hi @Muggins ,


The identity of the user opening the report is always passed to the underlying SQL Server Analysis Services source.

You need to set roles and RLS in SSAS for each user who needs to access the report.

This in know  issue when connecting to SQL Server Analysis Services (SSAS) or Azure Analysis Services.


Create PowerBI shared Dataset and provide the dataset access to users to conenct Excel or PowerBI Desktop for analysis  insted of conencting  SSAS cube.
