Hi,

In my opinion, you don't have to consider performance in writing an reporting event. Its the same whether you write a event at the top or bottom or inside an include.

But its a good practice to use a ordered approach as mentioned by you.

Hello,

Just to add to Kathick's explanation. ABAP is an event-driven programming language. The general flow of an ABAP program is controlled by events.

It is a good -practice to code event processing blocks in the order in which they will be triggered during execution. However, they do not have to be coded in a sequential order.

This is the first thing i learnt in ABAP basics class )
