Categories, like Work Types are linked to almost all records and events in SDI. Any record that allows time to be attached needs a Category, so system owners and managers can report on it.
Categories are created in hierarchical structures in Settings. Carefully plan your Categories before creating them. Link Skills to Categories where possible to enable Skills lookup for the Call Route Team or Project Managers.
Categories can be used to structure your inventory. Categories are used in the online Catalogue to structure navigation of products.
