Fetch Lease Schedules and Payment/Liability and other balances for all leases

Want to fetch data similar to lease details report for all leases in One file.
Lease Details Report, is attached at Lease >> schedule.
I couldn't find any table containing future data. however, that data is available at oracle UI also.
I need Amortizations Summary sheet data. I am able to fetch data till open period and historical data but requirement is to fetch future data as well.

If someone has any experience or idea about it. please let me know.
