When a project invoice is transferred or created in Receivables, the project sends only the invoice header and invoice line description to Receivables, not the invoice distributions. The invoice distributions contain the detailed information such as quantity, unit price, and line total. Therefore, the Receivables invoice does not show these details, but only shows a quantity of 1 and a unit price equal to the line total.
