SAP Netweaver Installation Plan

Hi all,

Apparently, I have SAP R/3 installed in a server (demo), and now, I wish to install SAP Netweaver into the box as well. What is the difficulties that I face, I am not so certain the steps or Installation Plan to have Netweaver installed.

I would appreciate if someone can share with me on what is the pre-requisite, installation steps/plan, and configuration of SAP Netweaver.

Many thanks in advance.

Regards,

Patrick
