Approval Workflow Setup for Purchase Documents

In Business Central, you can set up an approval workflow for purchase documents, such that the document will go through a process that requires someone to sign off on the data at a certain stage. Approval workflows might require multiple checks throughout the process and from a variety of different stakeholders. Business Central comes predefined with workflow templates that can be combined with the approval user setup to achieve the approval workflow business process. 

You can use the workflow templates to define workflows for purchase documents including quotes, orders, invoices, and credit memos. Workflows are carried out based on events and actions i.e. for every event, an action can be defined. The principle of actions and events can be used to define rules for workflows to meet common business process requirements.
