Editing a workflow rule in a workflow diagram

For more information, see Components of the rule expression language (in the Rules Reference Guide).

Use the Workflow Expression Editor dialog box to create the expression for a workflow rule in a Workflow Diagram tab.

Workflow Expression Editor dialog box—Option descriptions

Option	Description
Rule Name	Name of the workflow rule.
Rule Description	Description of the workflow rule. This field is not deployed. Maximum characters: 2000.
References section	Lists the components that are available for use in the rule being defined.
Show All checkbox	When selected, all available study objects as well as their properties appear. When not selected, only the available study objects appear.
Data tab	The available study objects appear in a tree structure similar to the Project Explorer.
Functions tab	The available functions appear in a tree structure organized by class. Note: Functions are defined in the Study Editor or Library Editor.
Constants tab	The available constants appear in a tree structure organized by class. Note: Constants are defined in the Study Editor or Library Editor.
Globals tab	The components of the available mappings appear in a tree structure similar to the Project Explorer.
Expression section	Used for developing the expression for the rule by typing or by dragging in components displayed in the tabs of the References section. When you drag in a component, the reference to the component is converted to the standard Central Designer expression syntax. Typically an expression might contain a combination of typed values (such as operators) and dragged-in components (such as functions or references to study objects).

Use the Invoke Function dialog box to assign values to the parameters named in a function you are invoking in a rule or global condition definition.

Invoke Function dialog box—Option descriptions

Option	Description
Function	Name and description of the function being invoked.
Return Type	Data type of the value returned by the function.
References section	Lists the components that are available for use in the rule being defined.
Show All checkbox	When selected, all available study objects as well as their properties appear. When not selected, only the available study objects appear.
Data tab	The available study objects appear in a tree structure similar to the Project Explorer.
Functions tab	The available functions appear in a tree structure organized by class. Note: Functions are defined in the Study Editor or Library Editor.
Constants tab	The available constants appear in a tree structure organized by class. Note: Constants are defined in the Study Editor or Library Editor.
Globals tab	The components of the available mappings appear in a tree structure similar to the Project Explorer.
Parameter Description section	Lists the parameters that have been defined for the function, along with spaces in which to specify their values in the rule or global condition expression.
Parameter	Name of the parameter.
Data Type	Data type of parameter.
Value	Value the parameter takes in the rule or global condition expression: An explicit number or string. A study object, constant, or data series dragged in from the Data, Constants, or Globals tab of the References section. A function that returns a value of the required data type (for example, the GetValue() function).
