Log a Call feature displays duplicate chatter feed posts when case feeds is enabled.
|Knowledge Article Number||000176415|
|Description||Customers who have the case feeds feature enabled have observed that when a user logs a call via the log a call publisher or via the log a call button on the activity history related list, they end up with duplicate chatter feeds, this issue is only isolated to the chatter feed, as duplicate "log a call" records are not created when cross checked on the activity history.|
This is currently working as designed and is usually caused due to workflow field updates on the task record, especially when the update is intended to auto populate a date field. The admin can run debug logs to identify the workflow in question responsible for the field update.
