Building in own OBS


I installed my own OBS in a VM. Then I interconnected to and used the template “JeOS KVM and XEN providing SLE 12 SP3” to create a new image. I want to test this image but I don’t know how to build it. If I use the public OBS I can see all build results for my Build Flags but in my own OBS there is a note “No build result available”. Did I miss any additional configuration?
