Additional ordering
For making additional entries for a GLU already generated and not settled yet (hereinafter referred to as open
GLU), enter the corresponding open GLU code and press the
GLU, then start item entries.
By default, when entering an open GLU code, the cash register does not check if the clerk code is the same as
the new order was made for the guest. If you want the register to check the clerk code, change the setting on
"PLU level shift and GLU function parameters" (page 67). When the code is not the same, the register shows
the error message "NO AUTHORITY" and does not accept additional order.
