EHP1 for SAP NW CE 7.1 and SAP NWDS Relation

Hi All,

I downloaded both EHP1 for SAP NW CE 7.1 and SAP NWDS Relation trial versions.

But when I read the installation process, there is no dependency between thesae two.

Why do we need both for BPM implementation?

Where and When will CE used?

Thanks,

Swapna.
