I need that my users have access to the sessions of the following way:

User 1 company1 session1
company2 session2
company3 session3

User 2 company1 session2
company2 session1
company3 session3

It's possible to do that?
Thank you,

I see you are on the BaaN-V series, so yes it is possible using the Role Authorizations.

I didn´t find the solution because if i put "full all permition" to one session the other sessions can be see by the user.

Can you help me?

I am not clear what is your requirement. If you have full authorization to all company level and you dont have a specific authorization at the session level then it gets the full authorization.

Refer to the chapter - Authorization Management System in the Tool Administator's manual.

Also refer to the posting -

Tools Question (http://www.baanboard.com/baanboard/showthread.php?t=14299&highlight=roles)

I want just the opposite. I do not give authorization to company level and I give to session level. I was giving always to company level.
Thank you very much.
