I have a SUSE Manager 3.2 installation and adding support for updating RHEL 7 Native clients.
I have the RHEL 7 client bootstrapped with the salt support ok and the RHEL 7 Server channels built and assigned.
The problem is that I need to restrict the minor version updates for RHEL (7.6, 7.7, ...) until the supported application is certified for that release level.

I tired using the recommended Red Hat tool "subscription-manager" to set the release version lock.
It works if I retrieve updates directly from Red Hat, but is ignored when getting updates through SUSE Manager.

Do I need to set up additional channels per minor release ?
Is there any other way to restrict updates to the next minor release level?

SUSE keeps it clear and simple with their SP level repos.
