How to do Explicit Enhancement

In case of explicit enhancement we can add our enhancements at any place as per our requirement.
Well in our case I don't have any standard program so I am using a Z program & enhancing the code.
Before starting explicit enhancement we have to create:

•   One enhancement spot.

•   In enhancement spot we have to implement spot.

•   All these task to be done under one package.

•   So I am creating one package in se80 first.

 
 1.   Right click & create Enhancement Spot.

 2.   Give the name of Enhancement Spot

3.   Now activate the enhancement spot

4.   Right click Enhancement Spots & implement it. 

5.   Activate the implementation, Goto SE38 & place the cursor where enhancement is require.
 
6. Enter Enhancement implementation name in Enhancement Spot name & Package name.  

  7.   Now enhancement-point will come in your code with Grey Fonts.

8.  Select Enhance

9.   Place the cursor on enhancement-point & create enhancement.

  10.    Give enhancement Implementation name.

11.  Place your code & activate. 

 12.  Now run the program you will find the enhancement.
