Manual entries for Inventory accounting

Hi,

Since there is no manufacturing accounting practised, we do not have interface with Inventory A/c's.  ie. We do  AP entries thru Procurement and Sales entries thru Sale order processing without COGS and there is no interface with inventory.

Can anyone help what entries need to be put if we want to update the Inventory a/c's ie Raw material, WIP and Finished goods for any period end.  We have the Consumption of Raw material for the period, closing WIP for the period and Closing stock of Finished goods.  How to update them in the inventory accounts in Ledger.
