Search internal table declaration using debug

Hi all,

I'm trying to track an information in a standard process and how everyone might to know it's a little trick because SAP likes to play with tables and values in their process.

So, I want to know if it's possible to create a breakpoint/watchpoint on debug to find when the table is declarated.

E.g: You start a debug and try to see the values on table nast. This table doesn't exist in your actual point on the logic but you know in some point between the standard and your zprogram it is pulled. So, I'd like to create a breakpoint/watchpoint when Nast starts to exist.

Is it possible?

Thanks,

Andréa
