In the MDrivenServer you can set Server Wide Variables :

If we find a matching variable name in your ServerSideViewModel the Server Wide Pre EAL will execute before the rest of your job actions.

This is a practical way to give your jobs information that are environment specific.

The normal use case is to clearly give information to jobs that this is a Production environment and every action can be executed, or this is NOT a production environment and thus you may want hold of exporting data och maybe export data to a different external system than what you use in production.
