After going through number of posts, I could not find a solution to my query.
I've created a query, assigned it to a role. Collected the necessary objects into a BEx Tranport Request. Assigned it to the correct package. Now after the TR has been imported into BW QA system, I dont see the query in BEx BWQ (Quality System). Do I need to transport the role too, to the BW QA system again (Role already exists in BW QA as well as PR systems)
