If you take a look at the documentation here:
You will notice that:
To use the full range of functions of the Business Package for MSS Add-On 1.0, you must have installed the following:
■SAP NetWeaver 7.02 with:
■SAP NetWeaver Portal
■Application Server ABAP
Does anybody know what functionality that will not be supported if you only have a SAP NetWeaver Portal 7.01 installed like we have?
