 The difference is that for single purpose vouchers the VAT rate is known already at issuance because it refers to a single purpose (service or product).

 The issuance of multi purpose vouchers is covered by the charge item case (`ftChargeItemCase`): `0x4445000000000060`. Since there is no specific product or service coverded by the voucher, the issuance is not taxable and no VAT rate must be specified. Same applies for redemption since the VAT rate is included in the charge items for the products or services of the request. For redemption of a multi purpose voucher, one can use the pay item case (`ftPayItemCase`): `0x444500000000000D` with a positive amount. If the cash register can not handle the redemption within a pay item, then it can alternatively use a charge item having the charge item case (`ftChargeItemCase`): `0x4445000000000068`.
