Iterating Option Sets, Choices, Options, and Choice Rules in Windchill 10.2 and Beyond
Creating and iterating option sets and choices follow this behavior:
Prior to Windchill 10.1 M020, when an object was created, it resided in the Default domain. When it was iterated (that is, checked in or checked out), upon a checkin that object was placed in the System domain. All subsequent iterations of the object were in the System domain, while the first iteration of that object remained in the Default domain.
If it is necessary to change access to the objects created prior to Windchill 10.1 M020, a Windchill business administrator must create Deny access rules in both the Default and System domains.
Starting with Windchill 10.1 M020, all objects are created in the Default domain, and their subsequent iterations reside in the same domain.
