@ArulDevan I tried to check how the document type validation is configured but couldnt get any result on it.
I want to use field level for filing date and no we cant make it mandatory as that is not the requirement.I just need to populate error msg on the property without using validation rule.
@ArulDevan once the user is trying to submit without adding a document type this error comes up. But there is no post validation getting done here on the flow action.
