However, this report does not pick up data retroactively; it must be configured to track changes in order to pick up such changes.
If your company is using a CATS (Cross Application Time Sheet) to record data, you may also access table CATSDB from transaction SE16. Field Process Status identifies a status. A record entered, then approved, then changed after approval will display each status providing an audit trail. The table can grow quite large.
If neither of these options apply, you may be able to find something at the Unix or server level, but that is beyond SAP.
