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).
