Is there SAP BW Best practices?

Hi SCNers,

I am new to SAP BW. I have been around the SCN for some time and came across many SCN post. People are talking about SAP BW evaluation/business demo scenarios like:

1.SAP Demo: DalSegno Company Lost Deals Scenario

2.SAP Demo: DalSegno Company Plan Data Scenario

3.SAP Demo: DalSegno Company Sales Data Scenario

These are some of the posts where its mentioned about the demo contents post 1, post 2, post 3 andpost 4.

And the link for these best practices or demo scenarios http://help.sap.com/bp_biv335/BI_EN/html/demo_page.htm doesn't work any more. Can any one please point to where it is moved now. I have already tried http://help.sap.com/bestpractices but could not find it. If it is there please help me to nail it down.
