Vyacheslav,

In addition to

PRICE
SKU
QTY

a 4th field PER VARIANT is required: "BARCODE" - UPC/EAN or whatever barcode format the merchant uses.

1. All the major shopping channels (amazon, ebay, rakuten, etc...) require a UPC or EAN per variant;
2. Any possible use of the cart for POS (point of sale) will demand a barcode associated with each variant;

The reason the barcode field must be different than the sku: can you remember the barcode # of an item? I can remember the sku of every item in my store because we use abbreviations and numbers for size and color. MLH12 is easy to understand, 899711001076 is not!

I know some merchants have added this as a customization to xcart -- it really should be stock. It's gonna be WAY easier for you to do this now, vs. individual merchants attempt to do it later.

Thanks,
J
