PeopleSoft Payables Control Hierarchy

A business unit is the broadest element in the PeopleSoft Payables system. All other entities fall beneath it in the control hierarchy. It is therefore the highest level from which default information can be derived. The system automatically uses the information that you specify at the business unit level unless you override it at lower levels in the application, such as the origin, control group, supplier, or voucher levels.

As you set up processing options at levels below the business unit level, notice that the first option for most functions is Default. Selecting this option points the PeopleSoft Payables system to the next higher level in the control hierarchy to obtain the value. For example, when you define voucher and payment options for voucher origins, you can have each category obtain the default values from the rules that are already defined at the business unit level.
