SAP NWDI - BuildSpace Components - Deployment

Hello Friends,

We are able to log-on to CMS and build (build request) the Development Components under BuildSpaces with out any errors.

Now the question are:

1. How can we build an .ear extension file for this build request using NWDI?
2. How can we push this build request code to QA and other target systems? I don't find a way on NWDI to push the build code on to QA...
3. Is it possible to push the build request components on to a track so that we can use the CTS+ transport approch in moving the custom code...

Thank you,

Sri
