You need to configure the required audit settings.

Enable Auditing on Columns (Options A and D):

Enabling auditing on specific columns like Dietary requirements and Email address ensures that any changes to these fields are tracked. This meets Terra Flora's requirement to log changes to these fields along with details of who made the changes and the timestamp.

Enable Auditing on Pet and Contact Tables (Options B and C):

By enabling auditing at the table level for Pet and Contact, you ensure that any updates to these tables, including changes to all associated columns, are recorded. This broad setting ensures full coverage of auditing for both tables.

Enable Audit User Access (Option F):

This option is recommended to track when users access certain data, which can help with compliance and monitoring user interactions with sensitive data.

Option E (Start Read Auditing):

Read auditing tracks when records are read. If compliance requires monitoring every time a record is accessed, enabling this could be necessary; however, the primary focus is on modifications rather than access alone.
