Reversing a PO 'Complete' status

Hi,

How do you reverse an accidentally set 'Transaction Completed(I1023)' status for service POs?

We have a number scenarios where the users accidentally set the status which in turn creates problems in the backend ERP system because we can't un-incumber the funds.

Do you have to write a custom program or is there something standard in SRM (version 5.0)? If it's custom program is as simple as either setting the INACTIVE field for the I1023 status or do you need to delete it or use some other technique?

Regards,
