Inventory Valuation vs Balance Sheet Error due to Average Cost
My inventory valuation summary and Balance Sheet Don't Match. It appears to be a posting error within my subassembly items where the avg cost is changing.
I have 3 items that are "sub" assembly items. Each item is built individual and tracked until it is incorporating into the next sub assembly item. Sub Item 1 is built, an increases Work in Progress. This item is incorporated in to Sub Item 2. When this item is built, Work in Progress is Decreased by incorporated item 1 and increased by the new sub Item 2. This continues for 1 more step until the final item is build into a new asset and posted to an inventory asset account labelled Finished Goods. There is currently a negative balance in my Work in Progress Account. When i compare the GL detail and the Valuation summary, it appears, that when each step of the assembly is built, the avg cost is changing as it is posted to the GL but remaining constant on the valuation summary. I can't adjust the items global value because it is correctly reflected. It is only reflected incorrectly on the Balance Sheet. Any suggestions on how to solve this error?
