If the EconomicContract terms specify pay-on-receipt.
The claims would be processed in the trading partners' 
internal business systems.

If the Economic Contract specified pay-on-invoice, 
then the business process would have another collaboration,
e.g. Process Invoice.  If the contract specified self-
invoicing, then there would be a Self-Invoice collaboration.
In either case, the receivable would be created based on
the invoice.

If students were reading the business process diagram
and explanation, they would know from the additional
note that I will put in based on this dialog.

I did not put an invoice in the process because, while
claims are part of REA, they are not yet part of the
UMM metamodel which is the foundation for ebXML
business process models.  We expect them to be
added to UMM at the next UN/CEFACT TMWG
meeting.
