OK, First of all thank you for your reply, I added new data elements and created new date set with these data elements, then go data entry screen and added new data on this data set that I am asking about how can I delete one record from added data?
I hope this section of the video answers your question:
It’s possible to fix and edit the entered data into a data set (and thus keeps an audit trail) of all edits and by which user whom then can be contacted directly.
