How to manage transport groups in SLD

Hi all,

I am facing some problems while trying to create/assign transports groups to the Business systems in my SLD. (i am using PI 7.0)

I have only 2 XI boxes (one for DEV and the other one for PRD) BUT my R/3 landscape consists of 3 environments (DEV, QA and PRD). I created 3 groups in the SLD but i had to assign every group to a Integration server, so i couldnt

Could you please give me some help about how to handle this kind of scenarios??

Any ideas or examples?

Thanks in advance for your support,

David de Miguel
