This documentation defines the term workflowin two ways.
Workflow is a system
Workflowis a system that was installed with Microsoft Dynamics AX. The Workflow system provides functionality that you can use to create individual workflows, or business processes.
Workflow is a business process
A workflowrepresents a business process. A workflow defines how a document "flows" through the system by showing who must process and approve it. For example, consider the following illustration of an expense report workflow. This workflow shows who must process and approve expense reports.
To better understand this workflow, suppose that Sam submits an expense report for $7,000. In this scenario, Ivan must review the receipts that Sam routed to him. Then Frank and Sue must approve the expense report.
Now suppose that Sam submits an expense report for $11,000. In this scenario, Ivan must review the receipts and Frank, Sue, and Ann must approve the expense report.
