[收藏]Demo on Enhancement FrameworkBy Jagadeshwar Gollap
Restrict users (sales persons) to view or change Sales order data - Using Enhancement framework:
Source Code Enhancement is one of the enhancement technologies available under Enhancement Framework. Implementing this technology is also called as Source Code Plug-In. Technically the source code plug-in implementations are stored in a separate include program and not as part of the original source program.
There are two types of Source Code enhancements possible.
- Implicit enhancement option
- Explicit enhancement option
Example Scenario:
One sales person can’t see or change another sales person’s sales orders.
In my program, I have used following users.
Sales person1 (user 1): lz8xzf
Owner for Sales order no: 174.
Sales person2 (user 2): lzn4rm
Steps to Implement the Implicit enhancement option:
Step1:
Go to SE38 and Open include MV45AFZB
Step2:
In order to implement any of these Source code enhancements, you need to be in
‘change Enhancement mode’ (the spiral icon available in the editor).
Step3: Go to EDIT option in the menu and choose Enhancement Operations -> Show implicit Enhancement Options 
All Implicit Enhancement option will be displayed. All yellow lines indicate Implicit Enhancement options. In ABAP programs, implicit enhancement options are predefined at the following places:
•
Begin/End of an include.
•
Begin/End of Method/Function Module/Form Routine
•
End of a structure
•
End of Private/Protected/Public Section of a local class
Step4: Place the cursor on the yellow line and choose
Enhancement implementation à Create. 
Step5: Give Implementation name and then create. 
Step6: Here Editor will be enabled to write the code. Write your own code save and activate it.
Step 7:
Once the development is completed you can test the scenario.
When Sales person (lzn4rm) tries to Open Sales order no 174, it gives error message ’Access Denied’.
Note: Sales order 174 is created by another sales person (lz8xzf).
