Navigate to the Admin > Properties dashboard and review the properties below.
Navigate to Approval Process > Approvals in the left menu.
If applicable, enable Approvals for Purchase Order and Vendor Invoice. The decision to use approval groups here is for either compliance or internal processes. For Vendor Invoices, you have the ability to choose from different levels of approval requirements.
Navigate to Purchasing > General in the left menu.
Check the "Allow Creating a PO without a PR" property.
- Note: the property setting "Allow users to delete unapproved PO/PR document" really refers to PO/PR documents with an In Use status only.
