No further results analysis versions can be created

Hi

In Sandbox system, I am configuring Cost object controlling to execute entire Production order cycle. While creating Results Analysis version in OKG9, I ran into following error.

No further results analysis versions can be created. See long text Message no. KQ173

Already 31 Results Analysis versions are present in this system. System is not part of any client's landscape but it belongs to SAP COE in my company.

I have created a new company code, controlling area & plant. I have been able to perform till overhead calculation and now I am stuck at WIP calculation.

Please suggest how to resolve issue.

In error message long text, under "Procedure" SAP has specified - "If central versions are marked for use as results analysis versions, and at least one of these has not yet been created as a results analysis version, the system offers the versions available in a display frame. Select one of these versions."

I do not know what is a central version.

-Thanks in advance
