We need to build review CVs based on entities users are responsible for

You will be able to leverage the entity security in your member formulas of your report. In the member filter of the cube view row or column, use the where clause to filter on a specific entity security setting. In the member filter example I have here, the report will only return entities that the user has read/write access to.
