Problems with security when using Live connection to SSAS Tabular

Hi

 

I'm working with an Oracle DW, SSAS 2016 Tabular models, and PBI for reports, eventually we'll go to PBI Service.

 

I need to implement security based on AD groups (read access rights) , and also by user (what can each one see), how should i do that? 

Will we have any advantage in particular accessing reports trough PBI service (connected to on-prem SSAS Tabular) or it is the same as connecting through Power BI Desktop? 

 

Thanks

Hi @Ricardo,

 

If you implement RLS on SSAS Tabular, once the report has been published, the dynamic row level security that was defined in the on-premises Analysis Services tabular model has been successfully reflected and observed in the Power BI service. Then Power BI uses the effective username property to send the current Power BI user credential to the on-premises data source to run the queries. So it should work seamlessly without problems.

Re: Problems with security when using Live connection to SSAS Tabular

Hi @Ricardo,

 

Based on my research,  RLS for live connections to Analysis Services are handled in the on-premises model. So you could implement security in the on-premises model. Please refer to the online document.

 

There are some advantages through PBI service.

 

  1. It is more effective to implement RLS in Power BI.
  2. You can do schedule refresh for the report in service.
  3. You can share the content to others in service.
  4. Different users could view the report at one time in service without having to open PBIX file in Power BI Desktop.

Hi @v-frfei-msft,

 

 

you wrote that "It is more effective to implement RLS in Power BI" - but now my doubt is, if i implement RLS on SSAS Tabular, and then move the reports to PBI Service, what will be the one that should be working, or will it work seamlessly without problems?
