Hello, I have Odoo 8. I go to Account -> Cash register and I open a cash with $0 initials.

Then, I do "Customer pays" and when I close the cash, I get the $0. Is there any way to log all the transactions in the period, for the journal of the opened cash? For example, if I do one "customer pay" of $50, when I close the cash I have $50...

Thanks!
