An expression is a combination of common mathematical values and Service Manager proprietary functions. You can use expressions in a search, quick action, dashboard, workflow, or business rule. The power of expressions gives you more control over your results. You can enter literal text constants, functions, or expression delimiters.
Six types of fields are supported by expressions:
•Boolean: Also known as a logical field. Used for storing Boolean values such as true or false.
•Number: Used for storing numerical values, for both integer and real numbers.
•Text: Used for storing textual (such as string) data, with support for Unicode characters and HTML.
•DateTime: Used for date and time values. You can optionally include time zone information.
•Currency: Used for currency values.
•Link: Used to link one object to another.
Four other field types are available in Service Manager but there are no expression use cases for them. You can refer to these types in an expression, but you cannot manipulate them. These are the following:
See Using Fields for complete information about these data types.
