At first, I explain what I want to do. We already have a quite complex tree structure at our company, so different departments want to start at different nodes when they start the PI AF tool. I thought that the "make root node" function can do this for me, but this only works temporarily. If I shut down the AF tool and start it again it always starts at the old root node again. But we want to have a certain branch as a root node. How could I solve this? Thank you very much!
