Use Your Salesforce Org’s Global Variables Everywhere in Flows
Access information about your org or the running user throughout your flows by referencing global variables. Previously, most global variables were available only in flow formulas, and Flow Builder displayed only the first 100 options for each type of global variable. Now you get all global variable options from anywhere in Flow Builder that supports variables. For example, you can easily display the running user’s name to personalize your flow screens.
