CC Expense Report Stuck waiting to approved by terminated employee

OIE

R12.1.3

A delegated person processed an outstanding CC Expense for a terminated employee

The resulting ER has gone to the terminated employee for approval and is therefore stuck.

We know that the workflow should not be set up to do this for terminated employees but what is the workaround?

Could we assign the ICX_HR_PERSON_ID of the terminated employee to a delegated user and then they can access the ER and progress it ?

If not whats the recopmmended way to resolve this ?

Many Thanks
