Power BI Desktop (optimized for Report Server) allows you to define roles with DAX filters. However, when reports are published to the Report Server, there is no way to assign these roles to specific users/groups, so we can't yet implement row-level security on the Report Server. It would be great it Report Server was able to support dynamic row-level security similar to the Power BI Service.
Hi everyone, We shipped this support in the January 2019 version of Power BI Report Server, which you can download here - https://aka.ms/pbireportserver Thanks so much for all your votes on this idea!
Please add the ability to Create Rolls and Limit data (RLS) In PowerBI On Prem the same as when publishing a report to the PowerBi website. Discussion URL: https://community.powerbi.com/t5/Report-Server/RLS-In-PowerBi-On-Prem/m-p/295252#M1812
This is the key feature which is required to reduce total number of unique reports else we will end up producing multiple report with data filters manually.
