BISM Tabular Dynamic Data Security Over Bridge Table

About four years ago, in my article Protect UDM with Dimension Data Security, I introduced an approach to secure dimension data in multidimensional cubes by using a factless bridge table. Since then, many BI practitioners have favored this approach because of its simplicity, reusability (transactional reports can join to the security table), and performance. Now that organizational tabular projects support data security, I wanted to try it with BISM Tabular. As it turned out, the factless bridge table approach worked out just fine.
