We recently updated to PDMLink 10.0, and discovered a new "feature." When checking in a CAD assembly, it automatically populates the WTPart BOM's Reference Designator field with the Component ID from Creo/Pro if there is no Reference Designator defined in Creo/Pro.
This is a problem for us. Reference Designators are used to identify electronic part instances, and they are used in mechanical assemblies to identify CCAs, switches, cables, flex circuits, etc. So many of our assemblies have mixtures of Ref Designators and Find Numbers. This worked fine in v9.1, but v10 apparently doesn't allow the field to be blank.
PTC support calls this "intended functionality" and hasn't yet found a work-around. They say it was added to "support enterprise top down design"
