Stock devaluation

Setting for most of our items are “Moving average price”. I would like to check every quarter by comparing actual stock value (moving average price) against last purchase price and/or against purchase price from trade agreements of vendors. Based on difference the system should give proposal for devaluation of current stock value and create automatically booking journal in Stock Management. Such function is available in other ERP software but is maybe not included in Axapta. Does someone have an idea to solve this problem? Regards

Big topic! Are you familiar with the Close and Adjust routines within Inventory periodic activities[?] You will need to use the tools in there to make any adjustments/revalations/corrections to exisitng entries.
