Create Delivery Note in Service

We have a requirement that every good that leaves our warehouse has to be accompagnied by a delivery document. This document must have a unique and automatically incremented number without any wholes. So I am wondering how I could do this for service repair orders using the Navision 4.0 Service Order Management granule?! Any ideas[?]

You could print the lines from the the invoice worksheet or from the service ledger entries and let the document carry the invoice worksheet no. or the service order no. Regards karl
