Is it possible to see a who has purchased an app in the iTunes Connect financial report? Our company requires to book every sale we make in our SAP system against a customer name. So when we publish the apps under our developer license, we will need the information of each customer who bought the app.

Is there a way Apple will give me detailed information?
No. The only way to get the name of someone who's purchased your app is to request it from the user when they open the app.
