Activate BC sets in system that has a production client

Configuring ChaRM in spro.

when I try to activate BC Sets I get an message:

"There is a production client in the system. SAP Change Request Management cannot be configured"

This is our production instance, and we have no dev or qa system, so we have no way of transporting in changes. The system is currently only used for Central User administration.

We plan to create a dev and qa system, but we need to get ChaRM up and running first.

Is there any way to get around this message?

Thank you!
