The Explore reporting tool helps you work with container data, but you can also build reports from bookings where no containers are assigned.
You can target just these bookings by selecting the filter Status: Booked
Each row will correspond to a booking and you can select all the itinerary columns that you need to build your report, for example Port of Loading, Port of Discharge, ETD, ETA.
Then you can export the data in the same way you would export container data.
This is particularly useful when tracking Exports where it is critical to get receiving window data before containers are assigned.
You can filter to see just US Exports by selecting the filter Trade Type: Export
Then you can select receiving window column like Early Return Data, Cutoff Date and export that data to make sure you're up to date on the latest details.
