Under the Extra Services in the interface area, you need to map the services created in GauVendi and your PMS.

It is important that if any extra service is created (meals, extra beds, services like parking, ancillaries, etc), that those are mapped with the right code from the PMS in this section. Just pick and chose the appropriate  option.

Failing to do so, will lead to the error messages and bookings are not synchronised with the PMS.
