You can easily locate a vocabulary of interest by performing a keyword search against any of its attributes (name, description, etc.). ![Vocabularies Reference Data](https://cdn.document360.io/dde9293e-c107-4b3e-9774-9c9c296ed970/Images/Setting/refdata-voc-new.png?sv=2026-02-06&spr=https&st=2026-11-10T21%3A15%3A49Z&se=2026-11-10T22%3A15%3A49Z&sr=c&sp=r&sig=e4tG46ZDIfpVnY1zu4odz4mxGg4kPpxOFNGuSAHtMRk%3D) You can only add and edit a vocabulary if you have the Reference Data Administrator role.
