I am working on a coexistence installation. This is with a rather large company with two major divisions. Business Data is not shared between the two divisions, nor are Control Tables, but the Versions List is shared. I already have a 2 CRP and 2 PROD environments for World (one for each division). In OneWorld I want to share the path code yet have 2 separate environments for PY as well as for PROD. Is there a tried and proven method for doing this? There must be other large companies using this kind of setup, how did they get up and running?
