Enhancement Implementation

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

Here I am explaining implicit enhancement. The screenshots in the explanation are for below scenario:
Extend materials (both header material and component material) to the plant while creation or change of BOMs.

Below are steps to create enhancement:

Step1:  Open include or function module to which you want to implement enhancement.

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: Goto Show Implicit Enhancement Options.   

Step4: Below lines consisting of double quotes(‘’) as shown in screenshot signifies that implementation is possible.

All Implicit Enhancement option will be displayed. 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  

Step5: Right Click on the line and Create Enhancement as shown below. The options to modify the enhancement is also available in the list.

 

  
 

Give a name and create.
An option to decide type of enhancement will appear.

In the example it is ’Code’.

Step6: The editor will open in editable mode. Plugin the code as required and activate it.

Step7: Test and see how it works.
