The C_REPOS_AUDIT table is stored in the Operational Reference Store (ORS).
If auditing is enabled for a given SIF request or event, whenever that SIF request is invoked or that event is triggered on the Informatica MDM Hub, then the audit mechanism captures the relevant information and stores it in the C_REPOS_AUDIT table.
The SIF Audit request allows an external application to insert new records in the C_REPOS_AUDIT table.

For example, audit an update to a complex object before transforming and decomposing it to Hub objects. For more information, see the
