The migration programs fill out the following elements based on incoming data: 

• PO Line type
• PO Entry Point
• PO Invoice Status
• Send date
• Expected receiving interval/date 

Post migration, Alma uses these incoming values (and possibly other values in the order) to determine the workflow status for a Purchase Order or Purchase Order Line.  This workflow analysis is performed on all orders and lines that are loaded to Alma via migration.

The initial set of rules used to determine these further statuses is not controlled by the customer; it is controlled by Alma Development. 

The following diagrams are very high level representations for the workflow analysis.  You can find out more about the PO Review Rules, and how to turn rules on or off, by consulting the page Configuring Purchasing Review Rules.
