Is this correct sentence? please confirm.
Shall I send the site wise break-up report to all or you only.
The sentence is not correct. This is because a question mark has been left out since the word "shall" has been used to indicate an action will take place in future. Find out more details at http://www.englishpage.com/modals/shall.html.
No, the word "shall" indicates there will be a question, but there is no question mark, and I don't understand what is being asked in the first place.Maybe...."Shall I send the sites "wise break-up" report to all, or you only?"
