I try to find out how to server two hierarchy schemas in SRM-MDM. Your suppliers even deliver catalogs in eClass or UNSPSC classification. In search UI I need now both in the search. So I built up two tables eclass513 and unspsc as hierarchy tables in MDM and filled them with the relevant data. In customizing of the search UI I do only see "Hierarchy" and "Category" as selection. How can I see my own hierarchy tables there?
