REST API: How to find Referenced by Part, starting with a known document?
Version: Windchill 12.0
Use Case: Using REST, I can start with a known ID for a WTPart, and find the documents that are linked to the part using /ProdMgmt/Parts/References. When starting with a known document ID, I cannot find an endpoint that will allow me to get the Referenced by Parts, even though using the UI, I can see them.
Description:
Is there an Endpoint for getting to the Referenced by Parts data, using standard end points, or am I stuck looking at a custom endpoint, or modifying an existing one?
