Component Matrix - Urgent SRM 5.5

Dear All

we want to implement SRM version 5.0 and SRM SErver 5.5.

We already have following landscape -

SAP R/3 - 4.7

Enterprise Portal - version 6.0

BW - 3.1

According to the Component matrix of Master Guide - SRM server 5.5 following is the matrix

SAP R/3 - 4.7

Enterprise Portal 7.0

BW version - 7.0

Now query is whether we can implement SRM server 5.5 and is this compatible with Enterprise Portal Version 6.0

and BW 3.1.

Or we need to upgrade the EP and BW components.

Can we go ahead implmenting EBP and SUS in SRM 5.5 with EP 6.0 and BW 3.1. Will there be errors ????

I will definetly reward points .

Regards

Nimish Sheth
