Approval trees are used in Accounts Payable to define the hierarchy for obtaining approvals for requisitions. With approval trees, the electronic route for the various users who must approve requisitions is specified. Approval trees can be created for particular buildings, departments, employees, types of goods or services requested, or other functions, and can include different rules (sequences) based on the total amount of a requisition or account numbers used.
Note: Each requisition must be tied to an approval tree, so there must be at least one approval tree defined in the system.
