When the Interface Table function is active, the AR Code is also used as a GL Key. If you have entered the AR Code A1, then A1 is also an AR Code GL Key.

The AR Code GL Key is attached to customers. You can use one code or as many as you want. Once the AR Code is created and applied to a customer in the AR Code box and a customer is selected in a transaction, the AR Code becomes the GL Key for the first position in the Interface Code.
