To actually manage IDMS/ADSO components with ChangeMan ZMF, a number of library types are defined within global and application admin, as illustrated in the screen-print here via the library types mentioned in red.
This screen-print also illustrates that the configuration of AbitMORE SCM for IDMS/ADSO is extremely flexible. For example there is no such thing as "sacred library types" for AbitMORE SCM for IDMS/ADSO. Just pick whatever library type mnemonics you want to use and enter them in global and application administration.
So if you don't like ADS as a library types to manage ADSO components, but (eg) rather prefer IAO, you can easily do so by entering IAO instead of ADS in the above panel.
