The Data Definition screen (Configuration>Setup>Data Definition) provides a useful resource for researching details about the data fields available in the OPERA database views and tables, without requiring extensive knowledge of database design. The information contained in the Data Definition screen can be useful when you are setting up a data extract for a mailing (Miscellaneous>Data Extraction), when you are setting up default field values for screens (Configuration>Setup>Screen Design>Field Defaults), or when attaching a user defined LOV group to a UDFC field that will be added by Screen Painting (see LOV Maintenance).
