Before navigating to your page, in your microflow set the DateAndTime attribute to [%CurrentDateTime%].
you can see below picture
i think the microflow works, my problem is the date and time only show in a new page(created by trigger, the trigger is last input finished), not the editing page
Hi, Srilatha, thank you so much for your help. To better understand my problem, please see the following pictures
you can see the result, i want the data and time fulfil in the editing page, however it appear in the new popup page, see below picture
