"Multiple invoices" for a Single order/delivery

We would like to setup "multiple billing documents" for a single order/delivery.

Regular order (OR), item category=TAN and Sch. Line=CP. Movement type =601.

For example,

We sold 1000 items to customer. Customer is the owner of the inventory.

u2022 Customer sells 100 items in Week 1, our company sends an invoice for week 1 for Qty=100

u2022 Customer sells 300 items in Week 2, our company sends an invoice for week 2 for Qty=300

u2022 Customer sells 450 items in Week 3, our company sends an invoice for week 3 for Qty=450

u2022 Customer sells 150 items in Week 4, our company sends an invoice for week 4 for Qty=150

We would like to bill periodically (weekly) as items are sold for one order/delivery. *How can we accomplish this??*

Same customer, same ship-to, same delivery date etcu2026.

Thank you,
