Typically, for a Flow, validation would be added via Flow Action. When I create a new Case with pyStartCase, the default out-of-the-box Flow for adding a new Case, I don't see any means to add validation.
We have a simple, one screen case details screen to be populate before (as) the Case is created. We need to validate that certain dates come prior to other dates.I don't see a Flow Action related to the pyStartCase Flow. Nor do I see any way to add validation on Case creation via the Case Designer or the Case Type rule.
How can I add validation to a Case on its initial creation screen?
