It is common in apparel industry to depreciate stock valuation of the products that belong to past seasons.
Is there a module to handle mass depreciation of the stock based on predefined parameters? Costing method is expected to be 'Average Price'.
Functions that I imagine are needed are as follows:
extension to the product master to keep year/season info
depreciation master to define the depreciation % for each product category + year/season
mass depreciation function that updates the costs of the products according to the depreciation master settings (there should be a wizard for user to select product, product category, year/season, and/or location)
generated journal items should keep the product name the entry originates from
