2 execute buttons

Hi Experts,

I found 2 types of execute buttons. Can you plese let me know the difference between these 2 buttons.

First button: On SE38 screen I found it(F8).

Second : By entering report name and click on Display button, I will enter into the report screen. Here a separate button for executing the report.

The purpose of both the bottons is same it seems.

Can you please let me know the difference between these two.

Thanks and Regards,
