WT-Parts Problem

Hello PTC Community ,

I`m working with the WT-Parts-Structure in Windchill. In our system the CAD-Documents are allready existing. I`m meanwhile able to create WT-Parts through "auto associate".

When I open the WT-Part-Structure through the function "show/hide" -> "CAD-Documents" all Referencedocuments appear e.g. the .prt-drawing and the .asm-drawing.

If I have for example a standard part and I create the associated WT-Part the Part-Structure also shows all the Assembly-Drawings where the standard part is used.

But I only want to see the .prt and the .drw-model of the standard part.

Are there any settings or filter options that I can use? Or is there already a mistake in creating the WT-Parts?

Thanking you in anticipation
