BOM Transformation not working for SubParts of WTPart

[Leon_Dietz]

I am using Windchill PDMLink Release 12.1 and Datecode with CPS 12.1.0.0

I created a new Subtype of the WTPart Object in Windchill, called 'Design Part'. With that I created a simple BOM with about 4 empty Objects, simply to test it out.
Now I am trying to change a BOM in Design view to Service view, however whenever I try to create a new downstream view of it, in the Service Associative Part Structure Browser, I get an error saying: ATTENTION: Downstream cannot be created. There is no valid relationship constraint between parent type 'Design Part' and child type 'Design Part'. And it does not work. When I try to do it with a WTPart, then it works just fine. So how can I create a downstream view with my subpart.

Here are the errors that I faced
ATTENTION: Downstream cannot be created. There is no valid relationship constraint between parent type 'Design Part' and child type 'Design Part'

Hi @Leon_Dietz 

Do you change configuration in Relationship Constraints Tab?

I would try to add own subtype.

Also there could be miss configuration on the subtype

subtypable has to be Yes if you want to use configuration from upper type. 

or you need to configure all additional consequence configuration for the specific subtype.
