_Cont'd from above post_: Just remembered (re-realized) that Kit items cannot be set as Standard Cost Valuation (or Lot or Serial), of which I _thought_ it was strange that some of the client's Kits were set as Standard. So similar to what's mentioned in the above thread, somehow these Kit items got incorrectly set as Standard Cost.

Why are Standard, Lot and Serial Valuation methods Not allowed for Sales Kit Product Type
Resolution
Serial, Lot and Standard valuation methods are not available to select for KIT type items.
This field setting defines the item costing method of a particular item and determines the cost value to be used in the GL posting. It is not designed for item tracking. The kit cost varies depending on whether the kit is exploded (shipped at the component level) or not exploded on Sales Order. A kit type item that is exploded uses costs that are associated to the kit components, not the kit item.
The component lines of a kit item that are exploded on the sales order may be changed on the order or during invoicing. This can significantly impact the item cost. The Bill of Materials module allows an item bill to be set up as a Kit. A kit type Bill may have Options that impact the item's actual cost significantly.
A costing method of lot and serial cannot be applied since the kit item is not being processed from inventory and no direct cost being associated to the Kit item. The need to assign serial or lot costing methods to assembled items can be met with the Bill of Materials module.
The Standard valuation/costing method is not an available valuation type selection for the same reasons as stated above. An exploded Kit item will use cost from the components of the kit not the cost of the kit item.
To create an item that is a ""Kit"" and be able to use the costing method of Standard, Lot or Serial, you must first create the item in Item Maintenance with a Product Type of either Finished Good or Raw Material and then create a standard type Bill for this item in the Bill Of Materials Module.
