What type of field allows you to look up values from one other table?

A 'Reference' field in ServiceNow is designed to establish a relationship between two tables, allowing a field on one table to store a pointer (sys_id) to a record in another, thereby facilitating data lookups and ensuring data integrity between related records.

'Verity' is not a standard field type in ServiceNow.

'Options' is a generic term, but not a specific field type that looks up values from another table; choice fields allow predefined options.

'Selections' is a generic term and not a defined field type that links to another table.

'Dot walk' is a powerful feature for accessing fields on a referenced record, but it is a data access method, not a field type itself.

'Lookup' is a general action of finding data, but 'Reference' is the specific ServiceNow field type that performs this function across tables.
