Status in SD document flow

Hi Experts,

Understand that from the SD document flow we can see all the related documents and their overall status.

May I know how the system checks/calculates (which table fields the system will check) the document whether it's a open or being progress or complete document for the documents listed below:

1. Sales order document

2. Delivery order document

3. Transfer order document

4. Shipment document

5. Billing document

And could you provide where is the configuration setting in SPRO for the above documents in order for the system know how/what to update in the document flow?

Thanks & regards,

Poi Yoke
