Removal of Weak-side Links
Out of the box, when an object is replicated, its strong-side links are removed while weak-side links are retained. However, there are exceptions: certain link types are configured to be removed even when replicating a weak-side object. These include EPMBuildRule, ChangeProcessLink, and ChangeReferenceLink.
For example, in case of an EPMBuildRule, the WTPart resides on the weak side of the link, and the CAD part on the strong side. Therefore, when replicating the WTPart associated with the CAD part, the link is removed.
Consider the following example.
In the example above, when WTPart002 is imported, the EPMBuildRule link between this part and CADPart001 is removed.
