If a Data Table component’s source collection is the output of a screen action, and the screen action’s autolaunched flow doesn’t set a value for the output collection, the Data Table contents are cleared. For example, let’s say that a Data Table component is populated with records from a screen action’s output record collection. Then, the screen action is triggered again, but this time the output record collection isn’t assigned any records. The records that were in the Data Table from the first time the screen action ran are now cleared from the Data Table. Previously, the records that were in the Data Table from the first time the screen action ran would remain in the Data Table
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the mobile app in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions. These updates affect flows only if they’re configured to run on API version 63.0 or later
How: With versioned updates you can test and adopt run-time behavior changes for individual flows and processes at your convenience. To change the run-time API version of a flow, open it in Flow Builder and edit the flow version properties. To change the run-time API version of a process, open it in Process Builder and edit its properties
