A product has a code. A lot may have another code. You should be able to select only the product or a product + a lot. You must be able to know current stock of a given product and current stock of a given lot. A variance should be a characteristic such as color or size, but a lot usually contains things such as when it arrived, an expiry date or even prices. > That say, you could have some kind of picking rules like FIFO (useful for > perishable products), those rules could be implemented in the system for > example with location order or (and I think it is the best) with > warehouse organisation rules (ordering the placement of products or > "take the older product"). Sorry, but don't get that. AFAIU you could not manage the case of two products with different lots in a single location? -- Albert Cervera i Areny http://www.NaN-tic.com Tel: +34 93 553 18 03 http://twitter.com/albertnan http://www.nan-tic.com/blog -- [email protected] mailing list
