When scrolling through a closed invoice, you get the following message:
“Invoice Closed No ACTION ALLOWED (Transh)”
This message will come up every time you try to scroll through the items in the list.
The problem lies with where the focus is allocated within the software as you are trying to scroll through the list. You need to allocate the focus to the list box by clicking the scroll bar. This will then give you the freedom to move up and down the list without the message coming up.
