Hi Uma
When OTM Audit is used, a seperate audit trail is used to track the changes made. So against the audited rate record a list of the audit history can be queried. The changes are recorded each time the change is committed and marked with the date/time.
As you drive into the audit trail - all the changes made in the same commit will be available for review.
Where updates occur, both the before and after values are available.
I have never used audit on Rates but it certainly works well for OBs and ORs.
