Limitations Of Object-Level Security In Tabular Models

Teo Lachev gives us the skinny on object-level security in an Analysis Services Tabular model:

Object-level security (OLS) is a frequently requested security feature when implementing semantic models. For example, a current project disallows some sales persons to see sensitive measures, such as Margin and Profit. In Multidimensional, modelers could use cell security to meet such requirements with the risk of compromising performance. Starting with SQL Server 2017 (compatibility level 1200), Tabular supports object-level security to disallow access to entire tables or specific columns without a performance penalty. As it stands, OLS has the following limitations (for a full list, review the documentation):
