Does the Costing Workbench play a direct role in Quote costing?

Okay, that confirms what I thought it was supposed to do for standard cost. (Except that PartPlant isn’t merely an optional override; it must exist.)

This is not what it does with the materials in a configured MoM. It appears to grab the first/any PartCost with a matching PartNum, ignoring CostID. I could not replicate the issue when quoting a part with a static/non-configurable MoM. I’ll try to replicate with a minimal configurable MoM.

To explain what I mean about PartPlant being required, say you have part P that uses material M, with a revision X in site A. To quote in site B, you need an alternate revision Y in site B. Part M must also have a PartPlant for site B, or the worksheet gets zero cost for M… insidiously silently.
