To view the properties of the Get All Document Changes subprocess, select the process in the navigator tree, then choose Properties from the Edit menu. The Get All Document Changes subprocess has a result type of PO Activity Performed, indicating that when the process completes, it has a result of Activity Performed. This result corresponds to the lookup code in the PO Activity Performed lookup type in the PO Standard item type.

This process activity is not runnable, indicating that it cannot be initiated as a top-level process to run, but rather can be run only as a subprocess when called by a higher-level process.

The Get All Document Changes subprocess is initiated when the PO Approval workflow determines that the document is a changed, not a new, document, and Archive on Approval is chosen for the document type in the Document Types window. (The change order workflow is not initiated unless you have chosen Archive on Approval. See: Required Modifications in Customizing the Change Order Workflow.)

The subprocess begins at node 1.

Node 2 determines the document type so that the correct subprocess (nodes 3 through 8) for gathering the document changes begins. For example, if node 2 finds that the document is a contract purchase order, node 3 finds all the changes in the contract purchase order. Nodes 3 through 8 find the changes by comparing the document with its previous archived revision.
