When an asset is disposed of, why isn't the book value zeroed out in the Asset Master record for each applicable book?

Costpoint Fixed Assets was designed to retain asset information at that data existed at the moment of the asset’s disposal.

This is a design issue. The system currently "freezes" the G/L Book and Other Books data before posting a disposal and does not write the resulting change as the result of a disposal back to the Asset Master book value fields. A complete disposal audit trail already exists without updating the Asset master G/L Book tab and Other Books Info subtask.
