You can set up the approval system to reflect the workflow of documents in your company. You can set limits as to what a user can approve (approval type: Approver), or you can require approval by the salesperson or purchaser responsible for the customer or vendor (approval type: Salesperson/Purchaser). You can also specify that you want to have the document approved by someone outside the 'normal' approval path (approval type: Additional Approver).
The following windows are used to set up the approval system: The Approval Setup, User Setup, Approval Templates, and Additional Approvers windows.
When you have completed the setup, you can run a test to see if the approval system works the way you intended it to. To run the test, click Approval User. in the Approval User Setup window.
