After some criteria are met, it is a good idea to mark the approval complete. Unless the approval was created with the Enable approval auto completion flag enabled, it is entirely up to the approval owner as to when to complete the approval. If auto-completion is enabled, the approval is automatically marked Complete when the last required approver approves.
The approval appears with a status of Completed, and
IBM® Unica® Marketing Operations sends a notification that the approval process is finished.
