Hi Anoop,
If you have followed the above process mentioned and have not found any exit then my guess is there is non. Another option you can try is to create an enhancement spot in the program ML01SFFC form FC005, I guess the table gets updated in this form routine. You can code what ever you want before the SAVE is executed.
You can find lot of text on Enhancement in SDN. Please go through the same before you do anything.
Regards.
