Code auto-generated by Generix POS — edit it if you'd rather use a scanned barcode as the code. This is the catalogue's own identifier, never a marketplace's SKU (see Amazon SKU below).
IMEI-tracked items always start at 0 stock — units are added one serial number at a time through Purchase.
Stock quantity after creation only changes through Sales, Purchases and Returns — it can't be edited here.
Links this item to that SellerSKU so future Amazon orders match it automatically — same mapping as SKU Mapping. Never the item's own Code above: this is only what Amazon happens to call it. Leave blank if this item isn't sold on Amazon.
