SD Billing Documents

[Johns, Ron E]

Workflow Experts,
 
In our Business we have a requirement to manage SD Billing Documents with
Workflow.
In laymens terms the requirement is to have an event at Billing Document
creation trigger a Workflow.
It is intended to forward the Billing Document to the Billing document
creator if the items are not cleared by the due date.
 
To meet this requirement I have planned the following:
A step would have a Required Start Date of the due date for payment of all
Billing Document Items in the Billing Document (or the earlist due date of
any of the Billing Document Items). This step would forward the Billing
Document to the "created by" user for follow up at the Required Start Date
of the step.
The terminating event for the first step would be an "all items at Cleared"
Status.
 
My problem is that I am not particularly familiar with SD and am having
difficulty with the following:
Which Object should I use for the Workflow?
How / where does SAP record item status's (it seems to be determined at
runtime of reports)?
How would I create an Event for the required Status?
 
 
Has anyone done anything similar? Even if someone has managed individual
items in a Billing Document your advice would be most welcome.
 
 
Regards,
