Expense reports with end date employee

Hello,

We are using using 12.1.3 and would like to know if anyone knows a process for the following:

When an employee leaves the company sometimes left with credit card transactions and subsequent expense reports that must be cleared.

This causes us to not be able to end date the employee as a user in Oracle and to not be able to terminate the employee in their person
record.  There is any way to have the expenses reports with the record end dated?

Thanks in advance for your help.

Kind Regards,

Paulo
