Product Vault and My Products do not allow a Case to be created which has Base Units with barcode numbers not in your number range e.g. an imported product. To create the case, select ‘Base Unit’ and put ‘case’ in the Description.
Don't forget to include the leading zero when you create your barcode image for the case - if it is not going through point-of-sale the GTIN should be 14 digits and the barcode should normally be ITF-14. But if the case is intended for retail sale itself e.g. a carton of beer it needs a GTIN-13 in and EAN-13 barcode.
