Issue about queries and BW Roles

Hi all,

I have a issue about BW queries and roles. I go to explain my issue with a example:

I have a unique role ZBW_ROL. This role has 3 queries, i.e.: ZQ1, ZQ2 and ZQ3. The role is assigned to the users USER1 and USER2, but I want to filter the access to query ZQ3 only for user USER2:

- USER1 only acces to queries ZQ1 and ZQ2

- USER2 access to three queries

Please, how can I do it with unique role? what authorization objects in PFCG t-code must I use?

thanks in advance

best regards
