Is it possible to define a Runtime System after the SC has been approved?

Question

Hello,
I have created a Track for a certain SC called TestSC.
When I did that, I defined only our development server as a Runtime System and imported the relevant SCs (SAP_BUILDT, SAP_JTECHS, SAP-JEE) only to this server.
Now, the TestSC has been developed, assembled and approved.
Is it possible, at this stage, to define the production server and import the TestSC to it?
The reason I am asking this is because at SAP tutorials you need to define these Runtime Systems in advance and import the relevant SCs (SAP_BUILDT, SAP_JTECHS, SAP-JEE) to each one of them before the actual development starts. If I will define the production server now, will I still need to import these SCs to the production server or only the TestSC I have created?
Thank you in advance,
Roy

Hi Roy,
for the systems DEV and CONS, you always have to import them, as without you won't be able to do development.
For TEST and PROD, there are at the moment no technical reasons for the import of these SCAs. But the CMS doesn't make a difference between SCAs that do not have to be deployed and the ones that have to be deployed (e.g. when you are working with external libraries that come in separate SCAs). The CMS transports all SCA that are checked-in and decides while the import what it has to do with the certain SCA (what can be three steps in DEV/CONS: import, build, deploy, while in TEST/PROD it's only deploy). This can also lead to the situation that no action is performed in a certain stage.
Perhaps there will be a version check implemented in later SPs, so that you will receive a message when trying to import SCAs from another SP level than your runtime system. Then it is mandatory to check this also in TEST and PROD.
