Expense Report not Appearing in Worklist and iExpense

Hi,

We have an expense report that was submitted.

From the Requestor's View, he can see that it is pending for approval by Approver X.

However, Approver X does not see it in his Worklist and His iExpense Home Page.

He also did not receive the email notification

He used to receive email notifications regarding Expense Reports.

I've checked the email address setups of PER_ALL_PEOPLE_F, FND_USER, WF_ROLES & WF_LOCAL_ROLES and they are all in-sync and active.

I've also checked the data in WF_NOTIFICATIONS and can see that it has the statuses of "SENT" and "OPEN".
