This functionality controls the "transformation" of Orders to Shipments, Orders to Invoices and Shipments to Invoices.

In v1 this functionality was controlled by the Inventory transaction records, special allocation tables and 100s of lines of code - probably the most complicated area in our design.

We have totally redesigned this area, eliminated all the allocation tables, moved the information for Quantity_Dues from the transactions to the bBusinessDocument_ProductLines, added super simple UI elements to support the functionality and used only a dozen or so lines of code [in BPs] to handle it.
