Analyze Metadata with the System Audit Log Report - the Currency Rates Tab
You can generate reports on metadata for currency rates.
The report will include information about whether a new currency rate was created, or whether an existing currency rate was updated or deleted. You can view both the original and the changed values, and the name of the user who performed the change. You can filter the report in several ways, for example on user, date and action.When you have generated the report, you can view report details by pressing Details. For information about how to interpret the details of the report, contact your system administrator or IBM® Cognos® consultant.
