Subscreen Activation on Material Master

The "Environment" subscreen on the Basic Data 2 view of the material master is not displaying even though the subscreen is defined in config (trans OMT3B). I realize there are other factors that make a subscreen appear, for example when you go to a plant view but don't put in the plant not all the subscreens will display. I tried debugging to figure out what I need to do to get the Environment subscreen to display with no success. Does anybody know what how to get that subscreen to display?
