How to get the invoice number on delivery document
i need your advise on the topics below it would be nice if you guide me to the right direction for implementing the system in Peru.
as in Peru they are required to follow the rules as their legal requirement for deliveries and invoicing
1) for every point of sale we have different number range given by government on a pre-printed form for delivery and invoicing,like we have four point of sales so that mean we have four different series numbers for deliveries and four for invoicing.
2) its government requirement to have delivery number on invoice.
3) we can have maximum of 22 line item or at the maximum 22 serial numbers on one delivery,more than that need to create a new delivery.
4) we can have maximum 15 line items on one invoice and 220 serial numbers on one invoice more than that we need to create a new invoice.
serial number of items on deliveries and invoicing are the serial number of the product and they are required to print them on the deliveries and invoicing,like if we have order for 22 items of same kind we need to print them with all the serial numbers on deliveries.
please throw some light on this.
