Assistce required for Updating Resource Usage UOM

Summary:

I have added a couple of resources using an incorrect usage UOM (NOS). These resources have already been used in some work order operations, and the work orders have been closed.When attempting to update the usage UOM from NOS to Hour, the system indicates that the resources are being used in work centers. Could you please advise on how we can update the usage UOM in such cases?
