Implicit Enhancement Option

Ø Implicit enhancement option

 

•     Throughout the ABAP system, enhancement options are automatically available at certain pre-defined places like 
• v      At the end of all the programs (Includes, Reports, Function pool, Module pool, etc.),   after the last statement
• v      At the beginning and end of all FORM subroutines
• v      At the end of all Function Modules
• v      At the end of all visibility areas (public, protected and private) of local class
•     To view all the implicit options available in a source code, menu path is
• v      Edit à Enhancement Operations àShow Implicit Enhancement Options
•       Place the cursor on any of these implicit options and choose ‘Create Enhancement’ from the menu to implement it .

 

 

      

 

Explicit Enhancement Option

 

ØExplicit enhancement option

wThere are two types of Explicit Enhancement options available:             

v   Enhancement Point- which can be provided at a specific place

v   Enhancement Section- can be used to replace a set of statements  

v

 

 

w   When the Enhancement-Section is implemented-- 

 

• v        Only the implementation gets executed and the original code doesn’t get executed
• v        It is a new technique indeed, which didn’t exist previously in any of the old ways of enhancing, to exclude any standard SAP code from execution                                              
• v        Because of this, there can be only one active implementation of an Enhancement-Section
• w   On the other hand, there can be multiple active implementations of an Enhancement-Point,                                                                                 
•      in which case all the implementations will be executed with no guarantee in the order of execution.
