We have several users with Accounts Receivable and Accounts Receivable Manager user roles. When they look at an open order with several still open order lines, click on "Invoice" - some see the list of Sales Order lines eligible for invoice, yet others see none. Filters are identical. The only difference is the appearance of "!" in an unnamed field under "Options", but it looks to be inert and doesn't display any error text:

On AX with a GUI, this appears to be a yellow triangle with the exclamation mark on board, which if you click it, will show an error message. On Dynamics 10.0.26, it appears to be completely inert. Any ideas how we get to know what's stopping invoicable order lines from being displayed?
