Possibility of Web dynpro ABAP development for SAP R/3 4.7 Version

Hi Experts,

I request for information regarding Web Dynpro ABAP. We have SAP R/3 4.7 as back end. And we are going to implement NetWeaver 2004s - Enterprise Portal 7.0 as front end. We are taking development option as Web Dynpro ABAP. Is it possible to do development in Web Dynpro ABAP where you have SAP R/3 version as 4.7.

Regards,

Venkat.
