This page provides details of the properties for the calculate action node and associated expressions. These are part of actionflows.
Overview
A gateway node controls the route that stream-items take as they flow through an actionflow. Decision logic can be specified on the output connection points to determine the path of each stream-item on a record by record basis.

Use this option to omit the action from the repository. Tick to display this action node in the repository. Untick to omit this action node from the repository. |
Input Connection Points
Shows a list of available input connection points. Gateway nodes can have
- one Driving input connection point
- multiple Lookup input connection point's
This section has a toolbar with standard buttons. The grid contains a list of all input connection points and their type.
- To add a new input connection point, in the section toolbar click Add New to open a new input connection point and set its properties.
- To edit an existing input connection point, double-click it in the list to open its properties.
- To remove an input connection point, select one and in the section toolbar click Permanently Delete.

Output Paths
Field | Description |
---|---|
Exclusive | Used to control if a stream-item can flow through more than one option. Tick the stream-item flows out the first connection point where the condition is met. Untick the stream-items will flow out of any connection point where the condition is met. |
Output paths process data using expressions; see pages in the topic Expressions and Scripts.
Gateways can have an unlimited number of output paths.
Stream-items will only pass through the output paths if the condition set in the expression is met.
Remember to check if if the gateway has been marked as Exclusive. Records will only pass through the first output path where the condition is met if the gateway is exclusive.
This section has a toolbar with standard buttons. The grid contains a list of output connection points and their expressions.
- To add a new output path, in the section toolbar click Add New to open a new output path and set the expression.
- To edit an existing output path, double-click it in the list to open its properties.
- To remove an output path, select one and in the section toolbar click Permanently Delete.
The expression properties has sections for Parent Details , Audit Summary and the following Basic Settings:
Field | Description |
---|---|
Name | Enter an expression name. |
Order | Where the gateway action runs and expression for each output path, enter a number to indicate the order in which this expression will be run. Remember that an expression that generates a value should run before an expression that uses the value. The order is especially important if the gateway is marked as exclusive. |
Expression | Enter an expression which evaluates to true or false to determine if stream-items will pass through this connection point. To work in a larger pop-up window, click . See also: |
