This is a minor UI annoyance but can lead to issues if an admin does not know ServiceMax well. When accessing an SFM Mapping, existing maps are not visible unless the user drills down by checking to see if any maps have been created in the past. If the admin does not know to check this picklist, then he/she might assume there are no existing maps created for this object combination.
I would like the maps to be visible when pulling up an object combination so that it's easy to see if any maps already exist. This is very helpful for troubleshooting.
