Rules provide comparison criteria that determine how an item is
routed in an application workflow. A rule consists of one or more field
expressions that are joined by logical operators. A field expression consists
of a field, followed by a comparison operator, followed by a literal value,
another field, or an application variable.
For example, to create a rule that evaluates whether the value of a
Numeric field is equal to or more than 500 but less than 1000,
create the following expression:
Amount >= 500
AND
Amount < 1000
The expression contains three panes:
- The left pane contains the field you want to evaluate.
- The middle pane contains the available comparison operators for the
field type.
- The right pane contains a field value editor that lets you specify
the value, field value, or application variable value that will be compared to
the field.
For example:
