We recently did a poc on Power BI but reach an dangerous limit of RLS feature. As we manage data from 2 organisations, we have 3 kind of user : User with access to org A; User with access to org B; ...
Like others, I am perplexed why there is not an option to "always apply Roles" to a dataset. The only alternative for a shared data source is to use Analysis Services and build the RLS into the cube. This is a huge hole in an otherwise good feature within Power BI.
