ME5A enhancement for new field

Hi Experts,

I have a requirement to add a custom field in tcode ME5A. I have searched and found some answer. ME5A Report - Request for Help | SCN

I have appended my new field in CI_EBANDB, but then how can I populate my new field? I need to use q query to populate the field.

But where here can I find any enhancement on how to populate the my new field in RM06BA00? Thanks
