We are using a workflow for managing User Access Request(to get new responsibilities) where approval hierarchy is set via AME rules.
Facing an issue, when approver has set a vacation rule and to whom the notification delegated happens to be the requester itself.
Notification contains an error message which says like: "Automatic route to <use name> failed. encountered during execution of Generate function 'WF_XML.Generate' for event 'oracle.apps.wf.notification.reassign"
However notification correctly displays its content and also the validation logic that we have put in post notification function while responding to notification is working correctly .
Also If the vacation rule is set to some user other than requester, issue does not appear.
Please guide if faced similar issue or any idea to overcome this.
