Material Classification - R/3 Fields

Hi Guys,

I am looking for 2 fields in R/3 in '1CL_OMAT001' (Material Classification DataSurce). They are available in our Legacy system datasource. I don't see them in our current R/3 system though. What we need to find out is whether or not they have been defined a classification characteristics in R/3. They may be defined and we just haven't added them to the datasource or maybe they've never been defined in R/3. How do we find out?

Any help will be greatly appreciated.
