Program Last Executed & By Whom

Hi Guys/Dolls

I'm trying to obtain information on when a program was last executed and by whom.

Having looked on this forum it mentions using transaction code STAT and STAD.

Are these the correct transactions I should be using to achieve my aims.

Unfortunately I'm not familiar with these transactions and need one of you guru's to guide me via a step by step procedure so I may obtain the information.

Many thanks in advance

Raj
