  • Disadvantage is that you cannot make use of "row level security" as all Cognos users will connect using the same profile (Data source has no information about current Cognos user).

This document describes how we can achieve security on the sales Area axis for the sales domain. Notice taht in this example, we are using Cognos as reporting tool.
