Implicit Enhancement for ME59N

Hello Experts,

I am working on ECC 6.0 and have implemented an Implicit Enhancement for one of my requirement for ME59n tcode.I am able to implement it succesfully and its working fine and its active also but, when I see the program where I have implemented the enhancement the code is not visible there until I hit the Show Implicit Enhacements button from Menu. I have followed the standard method for implementation as going through the menu option for implementing the enhancement.What could be the reason for this any idea?Why the code is not displayed in the program?

Thanks in Advance.
