Solution to close RFC manually when the previous doc has been closed

Hello,

I have trouble 'confirm' or 'complete' a few Req For Change (RFC) due to the
following errors: "The status
of the previous document cannot be changed". Currently, I have a about 30
of these RFC are in the status of "In Development" and I cannot move these RFC to
closure.

Is there a way to manually change status to 'confirm' or 'complete'?

I have added the 'Confirm' and 'Rejected' status but the system will not let
me close these old RFCs. I believe this is the result of closing the Change
Request or the Incidents associated to this RFC.

Any help would be greatly appreciate.

Thanks
