Trial Run Costing

koalado

We have lot of trial run production doing outside Navision, so high level expect to know the cost (material consumption and all other cost). Do I need to create new Item card for each Item? For example, create (Item-123-trial) for (Item-123) and link (Item-123)'s BOM and Routing to (Item-123-trial) and give it New posting group (Gen.Prod Posting Group, VAT Posting Group, Inventory Posting Group), assign finance account for posting group combination, so all the transaction could be recorded. Is this the best way? Any good idea? Thanks a lot.
