Micro-Action Rule

Currently in draft. Requires technical input from Eleanor and context input from Skevi.

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 Micro-Action Rule

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

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

Micro-Action Rule Properties

Use the following properties to configure the conditions or rules under which the micro-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/Micro-Action	The name of the micro-action. To add or change the name, do one of the following: select a micro-action name from the drop-down list of all SIAs in the repository. click Add New to create a new one; see Stream Item Actions (SIA) click Stream Item Action (SIA) to open the repository Streams branch to find a micro-action and drag it in. This makes it easier to find a micro-action for a specific stream.
Stop if True	If the following expression is true, stop the micro-action from running.?? If the expression is true run this action but do not evaluate any more stream item action rule expressions and do not run any more of the stream item actions.
Expression	Enter an expression. Details?? The expression should evaluate to true or false and the action will run if true. If the expression is empty this is equivalent to true. Values are true or false according to the same rules as true/false stream attributes, except empty is true (but an expression that evaluates to null or empty string is false).
Order	Specify the order in which this micro-action is listed in the action properties → Stream Item Action Rules/micro-action grid. PhixFlow evaluates the micro-action in order and runs those that evaluate to true in order.
