The final Sales Invoice
When advance invoicing is done, delivery dates for the goods will be scheduled on the Sales Order (COA) items, as normal. The Shipping Advice (CSA) that is used to ship the goods to the customer will also be created as normal, but there is a settlement between the final Sales Invoice (CIN) and the CINs made from the Advance Invoice Plan (CIP) documents. This means that the final CIN created from the CSA will be adjusted with the totals that is invoiced from the invoice plan. Each CIN item from the advance invoices will appear on the final CIN, but with a credit amount. The final CIN will then be for the total of the COA, adjusted by the credit amount from the advance invoices.
