How does data gets inserted in to ar_aging_extract table

Hello,

Can someone please let me know how does the data gets inserted in to ar_aging_extract in Oracle . I ran all the standard aging bucket reports but none of them is inserting the data in to this table, even i tried during the run time even then i don't see any data gets inserted. The reason i wanted to make use of this table is we wanted to customize the aging report and i thought it would be easy and best option to get the data from this table and build a query based on that.

Any help is much appreciated.
