Constants are global variables for a workflow that are defined on the Workflow tab in the Workflow Configuration window. Constants make it possible to change a value in a single location and have that change apply to the rest of the workflow.

There are three types of constants:

  1. Engine: Five Engine constants display in every workflow and an additional constant, IterationNumber, displays when the Workflow Type is Batch, Iterative, or Location Optimizer macro.

  2. Question: When the Workflow Type is Analytic App or Macro, many of the Interface tools display as Question constants. The name of the constant corresponds to the name of the Question tool. See Interface Tools.

  3. User: User constants can be created and edited via the Workflow Configuration window.
