Access Right on RTC

I have an issue on user configuration.

I have configured all permission on classic.

Users connect via windows login on RTC.

There are 2 companies on same dbs.

The issue is that I should allow a particular user access on Account schedule on company X only and not on Company Y.

Can you please guide me whether this is feasible??

Because when I change access for a user, it changes in both companies.

Thanks,

You can specify that a users has a specific security role per company. So you have to specify different roles for the same user per company.
