Windchill: Advanced BOM Transformation Topics

Hello,

Could you please verify the correct answer indicated in the training material?

Based on my understanding, the correct answer appears to be Option B – "Create alternate assemblies in the downstream view from assemblies in the upstream or downstream view."

However, the answer key indicates Option C.

Could you please confirm whether the answer key is correct or clarify the reasoning behind Option C?

It is from “Advanced BOM Transformation Topics” in MANUFACTURING BOM.
