Hello Rachirt,
From your problem i analysis only this much that a badi trigger before saving due to that a sting is append to material description and that text is saved in data base. for this i think if you find out what are the badi trigger before material save and make a note of that badis . and you have to check one by one badi codings by our cl_exit_handler->get_instance
as traditional put a break point in class cl_exit_handler 's get_instance method . after reaching for first time click F5 to get badi name.
use:-
With Hope this will Help in Solving Your Problem .
