There has been several occasions where I have went to check on the status of certain invoices or credit card transactions, and come to discover that the transaction has been 'Rejected'.

With this status, only the requesting user can make the appropriate changes and re-submit the request. I believe that a user with Administrative privileges should be able to address and make changes to these rejected items, or even delete the request, as it can become a serious obstacle to talk with each individual staff member and let them know that they will need to address the transactions in question.

If a staff member were to be on vacation or leave, some items could be left outstanding and no other user could take the steps to record the transaction other than the one who made the original submission.
