Go to function from task not going to parent record of Service Request or Change
Service Req and Change Object are not populating the parentlinkrecid for task. The ServiceReqAssociatesTask and ChangeAssociatesTask are set to a many to many relationship as seen in screenshot A.
It should be set to “zero or one” as seen in screenshot B. This will populate the ParentlinkRecID which will allow the task to be linked to its parent record. For existing records, it will need to be done from the backend for existing tasks to link these tasks to its parent record.
