Dears,
we have many cases that create a sales order ( will be delivered after one month), for logistical purposes, a sales invoice must be issued( Printed) and stamped by several official government offices, then send it to the customer to start payment process, while the products still in company warehouse, or under manufacture.
the second section is that when create many packing slip ( stock out ) , the packing slip must contain the above invoice number. finally create the final invoice the customer( that will be used aging and payment terms), the final invoice must match with the first invoice amount and quantity and with the many packing slips quantity, and the final invoice number must equal the first invoice.
first invoice = ( many packing slips quantity)= final invoice.
Note: the sales order may have many first invoices ( based on planned partially packing slip)
