Hi,
I missed to specify this clearly in blog: Developing Web Dynpro ABAP Applications using ABAP development tools (for Eclipse)
Now i have updated it there.
To summarize:
All these features for Web Dynpro ABAP development works with SAP NetWeaver AS ABAP 7.03/7.31 SP07 onwards, except for Floor Plan Manager Integration which works with backend version SAP NetWeaver AS ABAP 7.4 onwards
