Pay Below Paying Relationships
If you assign one phrase of a relationship type to the Pay Below relationship group, then relationships that you create using that relationship type are Pay Below paying relationships. A Pay Below paying relationship is a parent-child relationship where each party can pay for its own transactions, as well as the transactions of all parties that are lower in the hierarchy (children, grandchildren, and so on).
If the parties in the diagram shown in the Pay Within paying relationship section are in a Pay Below paying relationship, then all accounts of each child party in the relationship will be available to each parent party in the relationship for receipt application, commitment application, and so on.
In other words:
Acme Worldwide can pay for Acme USA, Acme Japan, Acme West, and its own transactions.

Acme USA can pay for Acme West and its own transactions.

Acme Japan can pay for its own transactions.
