CAD to Reference Designator of WTpart

HI all,

Is there a way to automatically create reference designators for a part with QTY>1, in the WTPart structure?

Iam checking in a CReo 2.0 assembly to windchill , WTParts are created as per the CAD structure, but the reference designators are missing in the WTPart (parent part).

I looked up the preferences and there seems to be none.

Iam using Windchill 10.2 and Creo 2.0

Thanks & Regards

Hari
