Contact, lead, and person account are three objects that will have the individual field available for tracking data privacy information when data protection and privacy is enabled for an org. The individual object is an object that stores data privacy preferences and requests for customers who are subject to privacy regulations such as GDPR; it can be linked to contact, lead, or person account records using the individual field. Case and opportunity, account and user, or individual, user, and account are not combinations of objects that will have the individual field available for tracking data privacy information; they either do not store customer data or do not support individual object relationships.

To use as an identifier when importing and updating records from a separate system, an administrator should use External ID field type on an object. External ID fields allow storing unique identifiers from external systems and using them for matching records during import or update operations. External ID fields can also be used for upsert operations that insert new records or update existing ones based on external ID values. For example, an administrator can create an External ID field on Account object that stores account numbers from an external ERP system and use it for importing or updating accounts from that system. Rich Text field, Record ID, and Auto-Number field are not suitable for using as identifiers when importing and updating records from a separate system.

Case escalation rules are a feature that can be used to meet this requirement. Case escalation rules can automatically escalate cases that meet certain criteria, such as being open for more than a specified time or having a certain priority. Escalation rules can assign cases to a different owner or queue and send email notifications to the support manager or other recipients.
