SAP ABAP Enhancement Spot: Tutorial and Best Practices

Best Practices:
Whenever requirement comes to enhance any transaction using enhancement spot

1. Go to SE93 and find the program name or go to the transaction and go to the screen on which you want to do enhancement. Go to system->status, you will see program name and screen number.
2. Go to this program from SE38 and open required screen number.
3. Search for Enhancement by selecting modules or forms available.  Here you need to understand the flow of the program, so that you can decide whether selected module or form is the right place to enter your code. Is it giving you the required output or there is any other module or form which is better than the previous one.

These are some of practices which you can follow while selecting enhancement spot for enhancement.
