SAP ECM VS CMIS

Hi All,

I wanted to know what features SAP CMS provides and what SAP CMIS provides.

I am verymuhch interested to know how CMS and CMIS integrate with SAP Protal role.

I know in CMS we can give read write and folder create permission to a specific group or role , but is this possible with SAP HANA CMIS?

Thank You.
