The AsyncActions.DuplicateBehavior Enum

The AsyncActions.DuplicateBehavior enum sets what AsyncActions.groupByRecord does when two actions in a batch name the same record.

AsyncActions.DuplicateBehavior behavior = AsyncActions.DuplicateBehavior.FAIL_DUPLICATES;
Map<Id, AsyncActions.RecordGroup> groups = AsyncActions.groupByRecord(settings, actions, behavior);

Values

Value	Description
GROUP_DUPLICATES	The default. Every action for the record joins one group and gets the same outcome. Use it when an action means only "process this record".
FAIL_DUPLICATES	Keeps the first action for the record, and fails the rest with SUDDEN_DEATH. Actions with no related record are never duplicates. Use it when actions for one record store different Data__c, since grouping would treat them as one request.
