Configure Action and Create 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 define a field that supports variables, automatically stored outputs show up as available options just like other variables in your flow. Later in the flow, you can access values returned by an Action element by starting to type the API name of the element.
To use the record Id from a Create 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).
