Customer Prepayments and Credit Check

Hello,

Do you know any hack to handle Orders for customers under Prepay ( Cash in advance) ?

The current process of my client is inefficient :

1- Customer issue a payment.

2- Payment posted as unallocated Cash

3- Order Released from Credit Hold.

4- Unallocated Cash Cleared with the invoice once the order is billed.

The idea is to avoid releasing orders manually for customers who already paid. I have seen in some other ERPs that the prepayment can be allocated to the order however with SAP S2 i can't find any possibility to handle that.

Thank you.
