How requests are generated (policies + workflows)
You rarely create an approval by hand. Instead, a policy — either a Workflow Management rule on a document type, or a chain configured on a request type — generates the request automatically when a matching document or internal request is submitted.
Understand the policy
In Workflow Management, a policy says e.g. “any PO over 50M routes to the department head, then Finance.” For internal requests, the equivalent is the approval chain configured on that request type (see below).
The source app triggers it
When a matching PO/expense/leave/internal request is submitted, the policy fires and creates the approval request in Approvals.
The chain runs
The request moves step by step through each configured approver; each approval, rejection, or send-back is recorded, and the source document’s status updates in lockstep.
