Set this Purchasing option in the Options Configuration window to Yes if you want to be able to flag items that have a promotion/temporary cost so that Inventory Maintenance is not updated with that cost. Once this option has been set to Yes, you can flag items in the Purchasing and Receiving window by displaying the item in the posting area, clicking Misc, and then selecting option P. The grid has a new field titled "Promo/Temp Cost". It will be Y if an item has a promo/temp cost; otherwise it will be blank. Finally, you’ll run the Receiving Report (RRP) with Update Prices option E ("Do not update cost with promo/temp cost from ERP") so that the promo/temp costs do not affect your Inventory file.
