Specify Domain Values

Domain values are the set of expected values for a term. Domain values are not used to validate rules. They are used to enable faster and easier rule authoring. They are displayed in the Expression Editor, which enables you to add a value to an expression by double-clicking on the value.

Domain values can include term or variable names. For continuous values, you can use the greater than (>), less than (<), and equal (=) signs to set limits for ranges. You cannot include a semi-colon (;) within a domain value. You do not need to enclose Character values in quotation marks unless the value itself contains an apostrophe (').

Separate individual domain values with a semi-colon (;).

Note: To enter continuous Date and Datetime values, enclose the values in single quotation marks, followed by a d or dt as shown in the following table.

The following table shows examples of domain values.
