This error occurs in two scenarios:
Double-clicking between invoice rows
If you double-click between two invoice rows, Finance Manager is unable to determine which invoice details to display, triggering this error.
To avoid this, ensure you double-click directly on the row and not between rows when opening invoice details.
Right-clicking on an invoice item
This error can also occur if you move the mouse immediately after right-clicking on an invoice item on the Pending Invoice screen.
To avoid this, left-click the row first to select it, then right-click without moving the mouse to bring up the options.
