Product code

Hi there,

in an ideal world the product code should be unique. However as we have discovered the real world is not so. We are testing uploading 16000 products from a supplier. The product code given is often repeated for the same type of product i.e. all chrome vanadium ring spanners of different sizes have the same product code. We have been considering the various options and I would appreciate your comemnts.

1) remove the unique index from the product_code field in the product table
2) use the barcode supplied as this really is unique
3) if there is an quick way to assign variants doing a bulk upload I could use this method

Thanks
