How to make the Laycan period in the Cargo Booking to match the Laycan period in the cargo?
The "Period Basis" field determines how the booking-level laycan will update the laycan(s) of cargoes within the booking.
If the Period Basis for the booking is set to "Default", the booking laycan will be copied as-is to the individual liftings in the booking.
If the Period Basis is unset, the total duration for the booking laycan is calculated to distribute the start of the laycan across the cargoes, and the individual laycans are recalculated based on that start date and the system default laycan duration.
