I want to reset multiple properties in a section to blank. I cannot find any standard activity or data transform. Kindly suggest. Also, if there is any other way apart from activity and data transform, kindly suggest those approaches too.
My answer is specific for couple of generic scenarios however the solution for this question may be case specific. Could you please elaborate how and when are you trying to reset the values .
If you are setting up a specific button to clear the values in the screen then you can use it to call an activity where we can reset the values to null and refresh the section this should clear the inputs given so far in the section you have refreshed.
If you are trying to clear the values of a section on submit of a button then we may use Validations or Post Activities of the specific flow-action that is being called.
