A configuration element is a list of variables, that you can use to configure constants across a whole vRealize Orchestrator server deployment.
You can use configuration elements to make variables available to all the workflows, actions, and policies running on the vRealize Orchestrator server.
If you create a package containing a workflow, action, or policy that uses a variable from a configuration element, vRealize Orchestrator automatically includes the configuration element in the package. If you import a package containing a configuration element into another vRealize Orchestrator server, you can import the configuration element variable values as well. For example, if you create a workflow that requires variable values that depend on the vRealize Orchestrator server on which it runs, setting those variables in a configuration element lets you export that workflow, so that another vRealize Orchestrator server can use it. Configuration elements therefore allow you to exchange workflows, actions, and policies between servers more easily.
