Using a base-supplied algorithm type, what is payment distribution priority typically determined by?

 The base-supplied algorithm type for payment distribution is called Payment Distribution - Pay Priority and Debt Age (PYDIST-PPRTY). This algorithm distributes a payment based on the age of each service agreement’s debt and the payment distribution priority of each service agreement’s type. The algorithm first pays off the delinquent debt of the highest priority service agreements, then the non-delinquent debt, and finally the new debits debt. If multiple service agreements have the same distribution priority, the algorithm distributes the payment proportionally based on the age of the respective debt on each service agreement. References: Distributing A Payment Amongst An Account’s Service Agreements, An Overview Of The Payment Event Creation & Allocation Process
