Spot dnf unsuccesful transactions

Using yum there was the chance that a transaction wasn't succesful, so that the next operation was blocked and the message told me to run yum-complete-transaction to fix the issue. What about dnf? Is there a way, maybe using a command like

-sh
dnf history info last | grep Return-Code    : Success

to understand if there are uncompleted transaction or event that requires attention and fix?
