I am using Fiori Apps. The workflow with standard workflow ID WS12300111 with new version of Agent Determination for task as General Task is used.
It is perfectly working fine in all cases like Leave Approval, Withdrawal and Rejection. It is not working only in case of Employee withdrawing the leave after the manager's approval. It is creating the workitem in the back-end and showing the manager in the agent. But it is not showing only in the Approve Leave Requests details page.
