Few queries on Enhancements ( BADIs or User Exits )

Hi Group,

I have started learning enhancements. I know a very little about this, but , the thing is that, I am not able to reach out to the exact Enhancement for the requirement.

For eg.,:

My approach is like when I want to use a User exit for any standard transaction, I will go to the status of the program and from there I am trying to find in <b>SE37</b> using the search criteria as "<b>EXIT_<prg_name>_XXX</b>".

But, when I use like this, some standard transactions, there was nothing as such appearing for my search criteria. Is my search false or is not there for as enhancement for my requirement??

I am very much not able to get to know exactly about which enhancement caters to my requirements, if one exists.

So please put in your valuable experiences on this topic.

Regards,

Vishnu.
