Variable Names
  • Spaces should not be used in variable names, however, you can use the underscore character.
  • Rule variables and workflow-level variables can have the same name.
  • Global variable names must be unique.
Global Variables

Global variables are system-wide variables that have their values populated during workflow execution and relate to the state of that workflow and its tasks. You cannot override the values.

Rule Variables
Rule variables are added to a rule at the Map and Calculate step (see Mappings and Calculations). Use the Formula Builder to create rule variables. You can add variables after a rule is created by accessing the Rule summary page (select a rule for editing).
System-Defined Variables

System-level variables are predefined and give users access to Workflows module information such as workflow ID. They can also be used in the Notify node and as assignments to other variables in the workflow.
