Currently there are error messages when using the Compare to CAD (and/or Compare to Part) function if the structure contains 1:N CAD to Part WTParts.
A typical 1:N CAD to Part is a set of WTParts with i.e. different color codes.
Refer to help center topic: Creating Alternate Structures in a New Product.
The idea is to have the possibility to use the Compare (to CAD/PART) function to verify the product structure,
And return no errors (or warnings instead) for parts with 1:N CAD to Part WTParts.
The Compare to CAD (Compare to Part) function typically used to verify the eBOM as a last step of eBOM creation.
