Hi Matthew,
Thanks for the reply.
Well, let me put mine views...........!!!!!!!!!!!
1. In the thread created by me,
I wanted to know, the table from where I can get the list of tables, which contain any particluar Data Element as its Key Field element.
And about self research, yes I did but unfortunately I landed into a System Call,
I have never ever posted any thread without self research ( after I started understanding ABAP ).
2. About posting URL, I really did not knew,
I could not find any such rule here ,,
http://scn.sap.com/docs/DOC-18590
so, next time you will not get any URL from me.
If you wish to disagree with these decisions, that is entirely your choice. However, the content will remain rejected.
Yes, dear I know......!!!!!!!!!!! 
But believe me, this thread was never intended to get back my post or thread.
But I just wanted to know the root cause.
I too understand the pain that moderaters would be facing, so I just wanted to get the real picture and not to repeat the same mistake again.
Thanking You All.
