Question: How are UPCs automatically generated?
Answer: The Automatic UPC Generation check box must be selected in Warehouse Management Control Maintenance. The Type A compliant 12-digit UPC or 13-digit EAN can be generated when adding a new product; but it cannot be edited subsequently.
For a single unit of measure product, select the Generate UPC Code check box on the General tab in Product Maintenance to automatically generate a single UPC.
For a multiple unit of measure product, select the Generate UPC at U/M Level check box on the General tab in Product Maintenance to automatically generate multiple UPCs.
To automatically generate UPCs in the Product Lifecycle Management module, enter a 5-digit sequential value in the field or grid column for the appropriate task (if necessary), then click the Auto Generate UPC/GTIN button in the ribbon in Lifecycle Data Entry.
