Pass User Email ID to Virtual Private Data Base

[pakhi]

Hi Team - I migrated few cognos reports from version 10.2.1 to cognos version 10.2.2. The backend data base is oracle. There is data base level security implemented based on virtual private data base. If I execute report old platform (Cognos 10.2.1) then I am able to see data for secured objects but when I execute from new platform (Cognos 10.2.2) then I am able to see data. The one difference I have in this whole migration process is the query mode. I just changed the query mode from 'CQM' to 'DQM' while upgrading cognos framework packages. Could you please suggest is there any specific setting required to pass user email id to Virtual Private data base in case of 'DQM' mode? I cross checked the data source property and it looks good to me.

Thanks,
Pakhi
