Menu Exit

 

A menu exit provides the customer with the option to include an additional menu entry with customer functions on an SAP screen without the need for any modifications.

 

 

Sap provides menu exits using customer exit technology or BADI technology. Menu exit can have only one active implementation.

Overview of Enhancement in the Enhancement framework

The enhancement options offered in the Enhancement Framework as of SAP Netweaver 7.0 as follows:

• Implicit enhancement points and options
• Explicit enhancement points
• Explicit enhancement sections
• New BAdis
• Classical BAdis

 

 

Enhancement points are points in SAP programs, function modules, and methods in which customers can add additional logic in the form of source code without making any modifications.

Implicit enhancement points are points in SAP programs where enhancement are possible, but where SAP development have not explicitly provided them, whereas explicit enhancement points are enhancement points provided by SAP development.

 

Enhancement options allow customers to define the following without making modifications:

• Additional interface parameters in SAP function modules and SAP methods
• Additional attributes and methods in SAP classes
• Preparation and post-processing functions for global SAP methods
• Replacement for global SAP methods

 

 

Enhancement sections are provided explicitly by SAP to allow customers to replace a block of SAP source code with their own logic, without the need for a modification.
