Select the invoicing date used for each generated invoice:

• Reference date.
  The invoicing date is the entered reference date. By default the reference date is initialized to the current date. It is available for modification. The entered date must fall into an open period (a control is carried out).
• Closing date for the request.
  The invoicing date is equal to the closing date for the service request associated with each invoice.
