Hi every one, I buy and sale products but to make it easy when searching for stock I have always had my own part number for the products I resale, but I have at least 3 suppliers for each of my products, each one with its own provider part number, is there a way that when I buy a product and enter it to openERP with its provider part mumber, my own part number show one in stock, no matter which provider I bought for that part? and without having to change part numbers when entering it.
