BPC 10 SP 5 : you have not logged on to central system

Hi Experts,

I am trying to add the new users to teams in BPC. The error I am getting is you have not logged on to central system.

But some of the business users are able to do the task.

BPC is integrated with CUA system. I have checked all the roles assignation also every thing fine.

Can some one please give the best solution.

Rgds
