In our situation a Sales order can have several Invoices (monthly basis). I need to determine at a particular point in time (comparing with the sales order):
how much has been invoiced;
how much has been paid;
how much is outstanding
- basic sum and difference calculations. With these value fields I can then build a datasource and subsequently join/combine with standard datasources to generate the required report
Report will have sales order id as key and will also link to some custom business objects I have built.
But my main question is about how to access the data in the BusinessDocumentFlow object.
