request stuck in move-pend status

I am not sure what you mean by stuck in Move Pend. You should be able to go to the Move Requests panel - option 5, and delete it from there, if you have move rights to that wrong environment. If you do not see the request there, then you do not have move rights. You will have to find someone who does, and they can delete it for you. My guess that this wrong environment has a Thru step of 2, so it is sitting at Move-Pend. This is perfectly legitimate and it not a bug.

Verify that the request has not completed to any Production Environment by going into #12-Request Inquiry and placing a 14-Target environments in front of the request. If the request has completed to any production environment, the lock will be gone and you will be able to re-check them out after you delete the request. If the request has not completed to any production environment, the locks are still intact. You will be able to create a new request after you delete the request or cancel the original request with the ICMPLRQS command.

Implementer 11.1 has a new functionality with the ICMPLRQS command that will allow you to mark the request as Canceled and provides a comment field for more detailed auditing. The older ICMPLRQS command simply marks the request as Complete without moving any source/objects.
