Stream-item-action Rule

This page is for application designers who need to configure when a specific operation will change data in the stream.

Record-Action Concepts

To make changes to the data in a table use a record-action. Each record-action is a single operation that can happen to a record in the table. Record-actions can create, read, update or delete a record, so are sometimes called CRUD actions. To configure PhixFlow to perform several operations to the data record-actions directly to a table. Alternatively, to configure PhixFlow to perform several operations

in one table, add a list of record-actions to a table or to a table-action associated with the table.
in different tables, add a list of record-actions to an action that is not associated with a specific table. The record-actions affect the different tables.

An action/table-action can potentially run any of the record-actions in its list. To decide which record-action to run, create a rule associated with each record-action. When the rule evaluates to true, the record-action runs, making a change to the data in the table. See Record-Action and Record-Action Rule properties.

Creating a Stream-item-action Rule

To use a stream-item-action in an action and to add a rule for it:

Open the Action properties.
In the toolbar of the Stream-Item-Action Rules section:
- either click Create New to create a new stream-item-action rule.
- or click Stream Item Action (SIA) to open a repository list of tables.
  Expand the branch for the table, then drag its stream-item-action into the action properties → Stream-Item-Action Rules grid.
  Double-click on row of the grid to open the stream-item-action rule properties.

Stream-item-action Rule Properties

Use the following properties to configure the conditions or rules under which the stream-item-action will run.

This properties tab is not available from the repository. It only opens from the Action properties.

For information about the properties toolbar, and about the sections Parent Details, Analysis Models, Description and Audit Summary, see Common Properties. We recommend you always add a Description that explains the purpose of the item you are creating.

For a full list of all the PhixFlow property tabs and windows, see Properties, Windows, Menus and Toolbars.

Basic Settings

Field	Description
Stream-Item-Action	The name of the stream-item-action. To add or change the name, do one of the following: select a stream-item-action name from the drop-down list of all SIAs in the repository. click Create New to create a new one; see Stream-item-actions click Stream Item Action (SIA) to open the repository Tables branch to find a stream-item-action and drag it in. This makes it easier to find a stream-item-action for a specific table.
Stop if True	Enter an expression. If the expression evaluates to true, PhixFlow runs this action. However, it does not: evaluate any more stream-item-action rule expressions run any more of the stream-item-action.
Expression	Enter an expression. If the expression is empty or evaluates to true, PhixFlow runs this action. To prevent an action from running in specific conditions, enter an expression that evaluates to false. The values that represent `true` are: any number other than 0 for a list: all items in the list are true the following case-insensitive strings `true` `t` `yes` `y` The values that represent `false` are: 0 (zero) any string not listed as true above including `false`
Order	Specify the order in which this stream-item-action is listed in the action properties → Stream-Item-Action Rules grid. PhixFlow evaluates the stream-item-action in order and runs those that evaluate to true in order.
