Use conditional actions and errors to transform data, display error messages, and execute other rules. You can specify that the actions should always occur, or define specific conditions under which they are performed.

 

All conditions are evaluated and corresponding actions executed, in the order they are defined.

​

Ways to define conditions:

• Always
• Match All - Specify one or more field comparisons. The actions are performed if all of the comparisons are true.
• Match Any - Specify one or more field comparisons. The actions are performed if any of the comparisons are true.
• Expression - Combine fields, operators, and literal values in an expression that is evaluated at run time to yield a boolean value (true or false)

Actions that can be taken:

• Update field - Choose an input or output field and set it to a literal value, copy the value of another field, or use a combination of fields, literals, and operators to define an update expression.
• Display Error - Create a message-expression that contains strings in single quotes, concatenated with field values. When the conditions evaluate to true, the message is sent to the user.
  • Click the magnifier icon to add template variables that supply data from the stream record.
  • Such variables have the form $DataComponent.FieldName.
• Execute Rule - Invoke one of the other rules defined in the system, specifying the mapping of local values to that rule's input data, and mapping fields in its output data to the fields defined in the current rule's data components.
  • Values can be mapped to fields in the input data or output data.
  • Values mapped to the input data do not affect the original incoming data, and they persist only until the rule finishes executing.
