We have a custom order type for our repair orders (ZRAS). We use tcode VF06 to create invoices for the sales orders nightly by a batch program. We have noticed that the invoices being created have multiple orders with different deliveries all on the same invoice. They belong to the same contract and customer. Our Billings department has requested that we enhance the invoice creation program so that only a single invoice is created per ZRAS sales order/delivery. Have any of you experienced a similar request as this and have any insight on how to go about doing this? The trigger would be off the doc type ZRAS.
