Hi waqas,
Its depend on the situation.
i want to share something at which condition i had use the debugger in the production system.
In my company Number range is different for the Production and Quality server.
In the ML81n TCODE when we get the package number & Subpackage number is always +1 of the package number. So we had just had the +1 package Number.But in production system the Number range may be changed or GOD knows what happens the difference between the package number and Subpackge number is 10 number instead of 1 .
So while testing in QA and Develpment Box its worked fine. But in Production it something is wrong.
So in that case we need to Use the debuger in the prod. server.
If the problem is not come on the QA and Develpment system its better to take the use the debugger in the production system instead of wasting the time.
Regards.
