One of the requests that I normally got in NAV or Business Central was the ability to do undo shipment or receipt on non-item lines, such as G/L or Resources.
When creating a Sales Order, some companies will also post G/L, Resource, or Charge line to calculate the freight cost. When they ship a Sales Order, the Freight line will also get posted and created on the Posted Sales Shipment.
If they need to undo the shipment, they can undo only the Item Lines. They will get an error message if they try to undo non-item lines.
Since 1 November 2019, you can now undo non-item lines on sales shipments and purchase receipts with the Undo Shipment or Undo Receipt button.
It sounds like a simple thing, but this will save a lot of work for users.
