A report is usually a self narrative of an event or occasion that has happened in the past or is currently happening. For report writing you need to have sufficient supportive evidences to tell readers about the different aspects of the events you are covering. It is not just the main event, but many other events happening around that you have to keenly observe. For Example, if you are reporting about a Cricket Match, you need to start telling everything from the players, to the game statistics, to the weather conditions, the pitch state and the amount of people attending the match. It involves writing about everything; from the central or main event to the minute details surrounding it.
