The ability for Evolution to identify specific lines that are going into negative when invoicing.
The following message "Negative quantity is not allowed!.[wtrg.1]" often paired with and SPE error is experienced when the clients are invoicing and certain lines on the invoice that will cause stock to go into negative. the above trigger is working correctly, just more information is required.
The problem here is that the invoice can have a 100 or 200 lines and the user does not know which item is the problem based on the current error message. Items have to be checked individually to identify the problem and once the problem item is adjusted the error only comes up again as the application does not tell you how many items are a problem.
by identifying all the problem lines the user can go attend to all and then invoice successfully in minimal time.
