A variable set contains all your Smart Preflight variables that can be used within your preflight profiles. You can create more than one Variable Set and each set can have multiple variables defined. However, you can only run one "active" variable set at a time per PitStop Server workflow. It is recommended that you keep all your variables within one Variable Set however this is not a restriction, just a recommendation.
To create a Variable Set click on the Windows menu from the main PitStop Server Window and select Variable Sets... or use the shortcut keys Ctrl + Alt + V on Windows OS and Option + Command + V on Mas OS. This will bring up the Variable Set Panel. This panel will display all the installed Variable Sets as well as any local Variable Sets that have been defined.
With the Variable Set Panel open, select the Action drop-down menu, and New from the sub-menu. This will open the Enfocus Variable Set Editor dialog using which you can create and open a new Variable Set that will be saved to your "Local" PitStop Server folder.
