Setting up Approval Processes
Various actions in the Order and Inventory Management product suite use the approval status to determine the actions that you can carry out on a record. You can create your own approval processes to determine when the approval status on a record is, or you can modify existing ones. You must create approval processes that are appropriate for your organization. To create a new approval process or change an existing one, click Create | Workflow & Approvals | Approval Processes. See the Salesforce Help for more information.
