The Before-After Data window of the Apply Regulation Guidelines configuration wizard allows you to select the tables for which you want to collect before and after data. You can collect before and after data for DML events generated by DELETE, INSERT, and UPDATE commands.
Collect before and after data when it is critical to capture the exact data change in a table column. When this feature is enabled, you can evaluate the before value and after value for each change in the Audit Events view. Enabling this feature can impact your Collection Server and Management Console performance.
If you want to collect before and after data, verify that you are auditing DML events on this database and that common language runtime (CLR) is enabled on the corresponding SQL Server instance.
To successfully audit specific columns on a table, ensure the table name does not contain the following special characters: \ / : * ? "
Select a database from the list and click Configure to open the Configure Before After Data Change window where you can add, edit or remove your specific user tables for Before-After Data auditing.
