We purchase many parts from a large distributor. Usually their products are a one-to-one match with ours, but as we are trying to implement contingency planning I am having an issue adding the multiple supplier product codes from the same supplier onto our Product. It seems like Sage does not allow you to use the same supplier more than once on a Product. For example I am attempting to add the yellow row in the picture below, but I get an error "Code already exists on line 1". This is in All>Common Data>Products>Product -- "Suppliers" tab.
How do other people manage this when working with a distributor who may send different part numbers for an identical product?
