Hi,
What exactly happens and at what stage of the process? Does any error message appear on the screen?
The only thing that prevents a Z from being done is if there is an unfinished transaction left on the till, if you turn back to R and press cash and see if the drawer opens.
If not try logging on as each of your staff member in turn and pressing cash on each, one of them should fire the drawer to complete the transactions and then you should be able to do your report.
Lew me know if you get sorted on this.
Thanks.
