ongoing development and bugfixing on same development system

Hi ABAP guys,

Does anybody of you know, if it is possible to separate bugfixing and ongoing development somehow in a 3-system ABAP stack landscape?

The question is if there is a way to do ongoing development (e.g. for the next release) and bugfixing on the same development objects in the same dev. system without transporting the ongoing development to the next system.

In Java development it would be done by creating a separate track. Can you use versions to do that or is there any other possibility or do you need to set up a second dev. system?

Thanks and regards,

Martin
