Typically, with most billing and management software integrations, you will need to be in the (appropriate club assignment, if applicable), appropriate department or have an appropriate title to appear in the DGR/DE lists, examples are Sales, Manager, Front Desk, etc. With some billing and management integrations, this is automatic based on what department or title is assigned there, with others, it requires manual entry in the VFPnext system.
Without an external billing & management software integration, the Staff should have the appropriate title, and the system should be set up to show that title in the DGR and DE.
