This page is for application designers who need to configure when a specific operation will change data in the stream.
Action Concepts
A stream has a set of Stream Item Actions (SIA). These represent the smallest, specific operation that can happen to the data in the stream.
You can configure one action to run on the data in different streams. This is because the action contains:
- a list of stream item actions (SIA) from different streams. The action can potentially run any of these SIA.
- with each SIA, is the rule that specifies the conditions for that SIA to be run.
To use a SIA in an action:

Properties
If you add or open a SIA rule, PhixFlow opens its properties tab. Use the following properties to configure the conditions or rules under which the SIA will run.
This properties tab is not available from the repository. It only opens from the Action properties.

Basic Settings
| Field | Description | ||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Stream Item Action | The name of the stream item action (SIA) To add or change the name do one of the following:
| ||||||||||||||||
| Stop if True | If the following expression is true, stop the SIA from running.?? | ||||||||||||||||
| Expression | Enter an expression. Details?? | ||||||||||||||||
| Order | Specify the order in which this SIA is listed in the action properties → Stream Item Action Rules grid. Order is important because, when evaluating the SIA rule expression, PhixFlow starts with the first SIA in the list. It will run the first SIA that it finds for which the expression evaluates to true. Subsequent SIA will not be evaluated or run. |
