What is Audit Trail in Siebel?

Audit Trail creates a history of the changes that have been made to data in Siebel applications. An audit trail is a record showing who has accessed an item, which operation was performed, when it was performed, and how the value was changed. Therefore, it is useful for maintaining security, examining the history of a particular record, documenting modifications for future analysis, and record keeping. Audit Trail logs information without requiring any interaction with, or input from, your users.
