Official definition

Booked means that the transfer of money has been completed between account servicer and account owner.

Usage: Status Booked does not necessarily imply finality of money as this depends on other factors such as the payment system used, the completion of the end-to-end transaction and the terms agreed between account servicer and owner.

Status Booked is the only status that can be reversed.
