Solman_Setup basic config - No free number range available

Dear Solution manager Gurus -

We have recently upgraded our Solution manager to 7.1 SP 11 (latest).

While doing

Solman Basic configuration in Solman_setup.

in Step 7- Maintain Systems in iBase, Step "Maintain number range for material", we get the error as "No free number range available.".

We have reviewed SAP note 1741109 - ITSM 7.1 - Generation of IBase Components is not working and followed all the steps.

However the error we are getting is "No Free number range available" is not mentioned anywhere in the above note.

I have also created OSS message for SAP to look at, no reply from SAP yet.

Please advise.

Thanks

-Lee
