Which source table contains information on User's project area Role access in RRDI?

Hello Samir,

according to the

Change and configuration management data dictionary
http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0m6/topic/com.ibm.team.reports.doc/topics/ccm-roles.html#Project-Area-Role

the role information should be available in:
Operational Data Store> Project Area > Project Role

According to the info center there is a part of the ETL that should be enabled to get this data:

New in CLM 4.0.5: The data collection job for Roles and Memberships information is disabled by default ( Ignore Roles and Membership Data = true ). If you set this property to false, no migration process is run. The next Common ETL job will load into the data warehouse the data of the project areas and team areas that were modified since the previous Common ETL job. To load all of the roles and membership information, you must run a full Common ETL job.
