Establishing Constant Data (Global Variables)

Overview

Decisions provide the ability to store constant values that can be reused in Flows called Global Variables. These are useful when the same data value needs to be changed in multiple places. The data itself is updated in one place rather than within each Flow that uses the data. For example, a user may use a global variable constant for a corporate address, a customer service phone number, or a standard email address in the Send Email steps. 

Example

The following example demonstrates creating a global variable used in the From field for an email address.

1. Navigate to System > Designers > Lookup Lists And Constants in the Decisions Studio. Click ADD DEFINED CONSTANT from the Global Action Bar.
   

   
   

2. From the Add Defined Constant window, enter "From Email Address" for the Flow Constant Name. 
3. Under the LOCATION category, enter "Email Address" in the List Name field and "Email Attributes" in the List Category Name field.  
   The List Name should refer to the name of the Project with which the Constant is affiliated. List Category Name represents the organizational body for the list. 
4. Under the VALUE category, select Flow Constant Type and enter an appropriate String Value (admin@decisionscom). Arrays are not supported as constant data. Click SAVE. 

   Flow Constant Type	Description
   Password	Masked String value
   String	String value
   Rich String	String value with available formatting
   Int	Integer value
   Decimal	Decimal value
   Boolean	Boolean (true/false) value
   String List	List of Strings value

   
   

5. Click CREATE FLOW from the Global Action Bar in a Designer Project and select Flow. Provide a Name and click CREATE.
6. Click the Done path of the Start step and select the Show PopUp step. Click ADD.
   
   
7. In the Subject field, enter "Constant Data Value:" on the Properties panel. Click Unknown next to the Message field and select Select From Flow. Click Email Addresses > Email Attributes and select From Email Address. Click DONE.
8. Connect the Done path to the End step. Click Save to save changes to the Flow.

Debug

1. On the top action bar, click Debug. Click START DEBUGGING.
2. After the debugger runs, the popup will display the subject and the email address from the Defined Constant.
