This field contains a code for the coupon issuer, which is the EAN number of the Issuer. This number is used to recognize the barcode scanned for the
coupon.
The code must be unique - you cannot use the same code twice in one table. You can set up as many coupon issuer codes as you want.
The value of this field must be in coherence with the EAN/UCC licence number of the Barcode Mask set up for
these coupons.
