BADI Introduction

Basic concept

SAP has introduced new enhancement technique Business Add-ins from release 4.6A.

Business Add-in is the new enhancement technique based on ABAP Objects. BADI is an exit point in a source that allows specific industry sectors, partners, and customers to attach additional software to standard SAP source code with out modifying the original object.

The users of Business Add-ins can customize the logic according to requirement or they can use the standard logic one available.

SAP guarantees the upward compatibility of all Business Add-in interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces.

Basic skills required

• Work Experience/Knowledge on ABAP Objects (Object orientation of ABAP) is mandatory.

• Experience on SAP enhancement technique.

BADI in detail

Business Add-ins infrastructure is multi-level system landscape (SAP, partner, customer solutions, as well as country versions, and industry solutions). Definitions and implementations of Business Add-ins at each level within system infrastructure.

Different Views

a) The different views of the BADI’s are:

i. Definition view, Application Programmer can predefine the exit points in the source in which specific industry sector customers can attach additional software to standard SAP source code with out having to modify the original object.

ii. Implementation view, the users of Business Add-ins can customize the logic they need or use a standard logic if available.

Architecture

a) User defined BADI’s:

i. First define a Business Add-In, application developer creates an interface for the add-in.

ii. Enhancement management creates an adapter class that implements the interface and thus provides the interface for implementation by the customer, partner and so on.

iii. The programmer/developer creates an instance of the adapter class in the application program and calls the corresponding method at the appropriate time.

b) Standard BADI’s:

i. For Standard Business Add-ins, the interface and adapter class will be predefined by SAP. The adapter class that implements the interface and provides the interface for implementation by the customer, partner specific to business.

d) Each Business Add-in will have one interface and an adapter class that implements interface. Depending on the business requirement user will implement the interface. The generated class (Adapter class) has the following tasks.

i. Control, the adapter class calls the active implementations.

Filtering, If the Add-in has to be executed under certain conditions, then the adapter class ensures that only certain implementations will be executed.
