Can someone enlighten me about what Mandatroy Patching menat to do. For what my understaning it should do the following.

You Create a group and add PCs to that group and then find the patches and create a baseline this would helps you keep all pcs to same patch level. It works as expected some sense but in the process it also makes a mess of bundle assignments say if you have 100 patches assigned to base line after you adding the PC to this group all your PCs will have that may paches directly assigned even after success full deployment of thos patches. I would expect the there should be no direct patch assignment to PCs only to group and when the PCs removed from group there should be no association any more. This not happening I am not sure if this is a bug or exected behaviour.
