i`m using SAGE 50 Premium CA 2020 ,
when i print invoice for partial delivery , all the items showing on the invoice will print. it might be possible to create a custom form which could hide back order items on the printed form.
No, in the internal forms designer does not have the ability to remove items that have already shipped in full. Customisations and printing of invoices outside of Sage 50 can make this option possible but it would require an add-on program that runs outside of Sage 50 to accomplish this task.
