Configure Screens and Get Records Elements Without Creating Variables
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
How: When you’re setting a field that supports variables, automatically created variables show up as available options just like other variables in your flow.
To use values from a screen component later in the flow, start typing the API name of the screen component.
To use values from a Get Records element later in the flow, start typing the API name of the element.
If you don’t want to use automatically created variables, select Manually assign variables (advanced).
