Are there any security reports that show to auditors an overview what has changed, for example changes to rules?

Answer

 

• There is a Security Audit Report that covers most changes.Even if there is not a standard report that you need, everything is audited in the database.
• For other items, go to System/Database, all the tables beginning with “Audit” contains all the changes, whether it be metadata, fx rates, rules.
• A Data Adapter can be used to generate a report.Very important: run these queries with a time filter, as there is a lot of data rows in some of these tables.
