Output Connection Points

This section has a toolbar with standard buttons. The grid contains a list of all output connection points. Each output connection point has an expression that specifies the logic to control whether or not records flow to the next action node. 

For driving output connections, you can refer to an attribute in the expression using the syntax:

Code Block
connectionpointname.attributename

Used to control if a stream-item can flow through more than one option. Todo-Fiona - Where does this property appear?

Output paths process data using expressions; see pages in the topic Expressions and PhixScripts.

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.

Note

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.
