EXIT is used to end a subprocess family. There are no restrictions as to where you can insert the EXIT statement within a process. You can control if it is to be executed by setting appropriate true/false execution conditions.
In this example, if the customer has a zero balance, the current subprocess family terminates and control is returned to the previous related or detached process.
