CMDB in SAP Solution manager

Hi all,

I wanted to know how was the integration between CMDB and Solution manager.

Is SAP IT infrastructure is mandatory to have CMDB in place.

Are there any documentation available on the how the integration of CMDB with solman?

In our landscape we don't have SAP IT infrastructure so Am looking only for CMDB along with solution manager.

Kindly guide .

Thanks,

Subhashini.
