redeem a voucher and block it for other POS

Hi Community,

i have a question to understand how the CCO handle redeem voucher database based in cco-manager.

Szenario: Multiple Customer want to redeem a voucher to the same time.

Is there a possibitly to reserve or block a voucher when it use in sales so that no other CCO-POS customer can use the voucher to the same time? How do the voucher database deal with multiple redeem voucher?

Thank you very much and best regards

Daniela
