This was a post on a thread of mine recently that speaks to the relationship with purchased parts that have methods. He said that if the “View as Assembly” checkbox is checked for a purchased part on a method, it is rolling incorrectly. That said, I would not understand why it would 0 out the cost if it was rolling those parts. But thought it might be a thread to pull. Maybe there was an update to the Costing Workbench Roll logic in a recent update like 2025.1.2…
