When mass-deleting Calls, a user gets the following trigger error: cannot recursively update itself
The user or process has both Parent Call IDs and Child Call IDs in the delete file at the same time.
Delete the Child Call records before deleting Parent Call records.
Note: Be sure that the Calls have been unlocked before deleting them. A Call can be unlocked by setting the Unlock_vod__c field on the Call to True.
