You must allow an item to be stocked at a location before you can post transactions for the item and location. For example, you must assign an item to a location before you can receive into Inventory Control a number of units and cost for the item at the location.
If Inventory Control does not use the Allow Items At All Locations option, you must assign items individually to the locations where you want to stock them.
You use the I/C Location Details screen to assign items to specific locations.
