Is it possible to use the DTR for EP 60 SP 2 and ME 2.1 development?

Hello,

a very simple question...

Is it possible to use only the Design Time Repository (DTR) as versioning source code management for development done on the SAP EP 6.0 SP 2 and Mobile Engine 2.1?

If yes, what kind of DTR client do I have to use(Eclipse-based Client, Command Line Client)?

For the development, we use Eclipse 2.1. Is there a plug-in for this version of Eclipse? If no, which version of NetWeaver Developer Studio do I have to use?

Best Regards,

Paolo
