Scenario on Enhancement Framework

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).
