It is possible to define global variables in InterformNG2, which can be read in all workflows and all templates. You can set a fixed value to such a global variable. This can be used in workflows and templates to identify on which machine the workflow/template is running. A related variable is the tenant variable. 

Please notice that if you define a tenant variable, a workflow variable or template variable with the same name as the global variable (case sensitive), then the value stored in the global variable will be overwritten in the current workflow and template(s).

You define global variables by first signing on as a system administrator in InterformNG2 and then select: Settings, General Settings and Global variables as marked below:

Now you will this:

You can add multiple variables with a matching value by simply typing them and click Save. You can rearrange the sequence by clicking the arrows on the right and delete a variable with the trashcan icon on the right. Save your changes by clicking the Save icon in the bottom.

You can refer to Global variables and Tenant variables in the workflow variable element in the designer and when you refer to variables in the workflow.
