Sometimes when you are entering transactions you might find that the customer, supplier, product or account code that you need does not exist. In this situation you can easily create the item then and there.

The code that you enter should be one that does not already exist, so the choices list will be displayed. If the code you entered does already exist the details of the item will be displayed—you should shift-tab back into the field and enter a new code.
The entry screen for the item that you are creating will be displayed.
