Define a Document Hierarchy
You must set up a document approval hierarchy in Oracle Purchasing before you can approve documents in Oracle Purchasing. A document approval hierarchy is not specifically required for budgetary control, but you cannot approve a document without some type of approval hierarchy. In some cases the approval options and document controls affect when you can reserve funds for a transaction. For example, if you are using requisition budgetary control, a requisition is not available to create a purchase order until it is fully approved (someone with enough monetary authority has approved it) and you have fully reserved funds for it.
