Try to get the Detail Information of the WTPart / CADDocument Representations via Rest Service API

Version: Windchill 12.1

Use Case: I use this URL to get Info on the Reporesenation attached to the wtPart and the attached CAD Docs: https:///Windchill/servlet/odata/v7/ProdMgmt/Parts('<wtpart_id')?%24select=Name%2CNumber&%24expand=PartDocAssociations(%24expand%3DRelatedCADDoc(%24select%3DNumber%2CName%2CCategory%3B%24expand%3DRepresentations))%2CRepresentations.

Description:

I use this URL to get Info on the Reporesenation attached to the wtPart and the attached CAD Docs: https://<Windchill URL>/Windchill/servlet/odata/v7/ProdMgmt/Parts('<wtpart_id')?%24select=Name%2CNumber&%24expand=PartDocAssociations(%24expand%3DRelatedCADDoc(%24select%3DNumber%2CName%2CCategory%3B%24expand%3DRepresentations))%2CRepresentations.

What I am missing is the Information from the Details column in the Representationn/Annotations table on the Part Information Page. (see attached picture) Is there a other Rest Service API to get the information (Positioning Assembly / EPM only /EPM latest / Derived/Copied from)?
