We can have a workaround for this. 1.To iterate, use ForAll function in PowerApps. 2.Get the data table entries into a collection 2.1 Have an invisible gallery who's item property is set to your datatable 2.2 Have a button and set it's OnSelect property as ClearCollect(yourcolname,gallery.allitems) 2.3 Now you have your collection 2.4 Use ForAll(yourcolname,Patch(destinationtable,Defaults(destinationtable),{columntoupdate:yourcolfieldname.value}))
Hope this solves!
