 The difference is, that for single-purpose vouchers, the VAT rate is known already at transfer (issue) because it refers to a single purpose (service or product). On the other hand, in case of multi purpose vouchers the VAT rate is not known because it can be redeemed for different purposes (goods or services).

 The issuance of multi-purpose vouchers is covered within the pay items by `ftPayItemCase`: `0x444500000000000D`. Negative amounts get converted to an issuance. 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 `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 `ftChargeItemCase`: `0x4445000000000068`. 
 
 Furthermore for the issuance of multi-purpose vouchers, one can alternatively use a charge item instead of a pay item. The `ftChargeItemCase`: `0x4445000000000060` has to be used.
