So, once in a while it comes in handy to be able to express a SET as a combination of resources already found either in SET A or in SET B or…
For example, when doing Access Granting MPRs it can prove very useful to be able to create only one MPR that applies to a number of different users (expressed as separate SETs). The simpler the better, right?
So, I wish to create an MPR that grants access to some Homepage resources, but grant access to that for 2 sets of people. These 2 sets are seen below (LineManager and HR personal).
The superset is created in this way:
User that is Resource ID in <SET A>
User that is Resource ID in <SET B>
