By manual, if you mean giving goal and deadline directly to the assignment & giving action in case type itself, then yes it is working absolutely fine.. but dont understand whats the issue with it when I pass the goad deadline through local action & then call an escalaction action
Assignment instance and it's SLA instance are created when user first time lands on the assignment. As you are processing a local action , it does not recreate the assignment and thus the SLA instance is also not created. So, the new goal and deadline time is not updated. Please add a connector which will leave from the assignment and reach the same assignment. Use the local action flow action in the connector. This way, the assignment and SLA queue instance would be recreated.
