Dual Control for Customer Master Records

Hi !

Has anyone used the Dual Control functionality for customer master records?

SAP documentation simply states that the system will place a payment block. However a 'payment block' makes no sense for customers. For a customer who has an outstanding change that is yet unconfirmed, we were able to create a sales order, delivery, PGI and invoice. Surely the system won't prevent us from applying cash.

The Dual Control functionality makes sense for vendors, but we are somewhat baffled by this function in the context of customers.

If anyone has any insight into this, please advise.

Thanks,

Anisha.
