I created a couple Lot numbered Assembly items (I'll call them A and B) using standard cost but did not define a cost during item creation. When I attempt to build an assembly I am getting an error saying "Inventory Revaluation is no longer the first transaction in the item's history." This assembly is complicated as we make a large size (Item A) then transform a portion into smaller sizes (Item B) via Inventory adjustments. I have calculated what Items A and B should cost but I don't know how to assign that cost to the items after creation. From what I'm gathering, an inventory cost revaluation would include the cost of all the BOM components that go into the assembly of Item A but using this method won't translate those costs correctly when I go to split A into 10x as many Bs.
