Required. Found on the Inception tab. By default this is the same date as the Begin Date. You may enter a different date to cause the lease to be recognized for reporting purposes as of a different date. Use a date later than the Begin Date if you didn't receive the information on the lease until later, and reports were run for intervening periods. Use a date earlier than the Begin Date if the lease is signed but use of the asset is delayed to a later date.
If the Booking Date is later than the Begin Date, then the lease is first reported in a report that includes the Booking Date, at which time all activity from the Begin Date to the present is booked (“catch-up accounting”). If the Booking Date is earlier than the Begin Date, and the system option "Include future leases in future minimum rent commitments" is checked, then a report that ends on a date between the Booking Date and the Begin Date will include the lease in the future minimum rent commitments, but not on the income statement or balance sheet.
