    Business Add-Ins


    BAdi Definition

    BAdi Implementation

    Calling BAdi

    Filter Dependent Badi

    New SAP enhancement technique

    To accommodate user requirements not available / too specific to be included in the SAP standard Program

    Based on ABAP Objects – It has Interfaces & Methods

    Guaranteed 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

    Though different enhancement technique, BAdi has following distinct features

    -Uses Object oriented approach

    -Two parts - Definition and its Implementation - definition can either be SAP provided or user may also create it

    -no longer assumes a two-system infrastructure (SAP and customers)

    -allows multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like)

    -Can have multiple representations – specific one will be executed based on some criteria (filter)

    -No SSCR registration

    Application Programmer defines an interface for the Business Add-Ins

    Enhancement management takes this interface & generates an adapter class for implementing it, thus opening path for implementation

    As per need, BAdi is suitably implemented

    Developer then creates an instance of the adapter class in the application program and calls the corresponding method at the appropriate time

    Application program simply calls the adapter class methods; it does not know which implementations are actually being called

    Adapter class methods generated by add-in management decide which implementation is to be called

    Look for BAdi in IMG and in component hierarchy

    Create own implementation of the add-in (complete coding for Methods) and activate

    Enhancement's active components are called at runtime.

    BAdi Definition

    To include Business Add-Ins in the program

    - Define an interface for the enhancement in the SAP menu under Tools-> ABAP Workbench -> Utilities -> Business Add-Ins (transaction SE18)

    -Call the interface at the appropriate point in application program

    -Customers can then select the add-in and implement it according to their needs

    Let’s plan a simple task:

    We want to convert strings in your application program is a specific way through Business Add-Ins technique

    As the application developer, first task is to define an enhancement consisting of an interface & a method with a changing parameter to transfer value

    Choose Tools ->ABAP Workbench -> Utilities -> Business Add-Ins (transaction SE18) from the SAP menu

    Create a new Business Add-In containing a maximum of 20 characters and move to Interface Tab

    Name of the interface is proposed by the system but may be changed

    Save and double-click on the interface name to add a method

    System branches to the Class Builder

    Assign a method to the interface (default is Instance Method)

    Add a parameter

    Save and Activate

    Definition screen(SE18) will now contain the method assigned to the interface

    Documentation may be created to describe the intended functionality of this Add-Ins

    BAdi Implementation

    ABAP Workbench ->Utilities -> Business Add-Ins (transaction SE19)

    Find the suitable Business Add-Ins present in system (Use IMG or Component hierarchy)

    Use Add-Ins Documentation to understand functionality & to decide

    Implement the Add-Ins

    -a class is created with the same interface

    -Finalize coding for the method

    Implementations are discrete transport objects and lie within the namespace of the person or organization implementing them

    Work on Simple Badi project – Continued…

    Already structure of the interface defined

    In order to create an implementation for the text conversion example, the add-in (in this case, the interface's method) needs to be filled with logic that converts the string. This logic will be run through every time the add-in is called from the application program

    Choose ABAP Workbench ->Utilities -> Business Add-Ins (transaction SE19)

    Create a new implementation and select the appropriate definition in the dialog box

    Add a short text and move to Interface tab


    Double-click the method name when the system will take you to the code window for the method

    Insert the desired source code for the implementation between the method if_ex_businessaddin~method. and endmethod. statements automatically provided to you by the system.

    Save and return to the Change Implementation screen

    On Activation, this implementation may be executed from the application program

    Sample code to call Add-In from ABAP Program

    To call static method of a global class directly, class … definition load statement is needed

    Instance of the Adapter class is created and its method is executed

    If enhancement needs to be different based on some parameter (e.g. country-specific or company-code specific), separate implementation of the same Add-In can be created and activated

    At run time, the specific implementation will be execute

    Possible through Filter-Dependent Badi

    How it works

    -Switch on Filter-dependency while defining the interface

    -Select a suitable filter element

    -All methods created in the interface will have filter 'FLT_VAL' as one import parameter

    -Application program provides the filter value to the enhancement method

    -The method then selects the active implementation for that value

    What qualifies as a Filter

    A Data element

    Underlying domain may contain a maximum of 30 characters and must be of Character type

    The data element must

    -Either have a search help with a search help parameter of the same type as the data element and this parameter must serve as both the import and export parameter or

    -the element's domain must have fixed domain values or a value table containing a column with the same type as the data element

    Custom data element with the criteria may also be used

    Implementing a Filter-Dependent Business Add-In

    Implement the Add-In for each relevant filter value

    However, multiple filter values may use the same implementation

    Enter a characteristic filter value for the implementation

    Calling a Filter-Dependent Business Add-In

    Same as before

    Pass the filter value as export parameter to the method

    BAdi – some useful information

    There can be more than one implementations of the same BADI definition, and in that case only the active implementations will be executed

    You can activate or de-activate any of the implementations after creation

    Enhancement, interface, and associated classes generated all lie in the appropriate application development namespace

    Business Add-In implementations lie in the respective namespaces of the people who created them

    Changes made to the interface and changes made to the Business-Add-In definition are always incompatible

    -If implementations already exist for a Business-Add-In definition, they are invalidated if you make changes to the interface. This means that their syntax is no longer correct. No statements can be given on the runtime behavior. Avoid making changes to the interface or the Business-Add-In definition after the transport has taken place.

    -If changes to the interface are inevitable, navigate to the Class Builder for all implementing classes and clean up the method includes of these classes (Utilities > Clean up > Method includes)

    Please give me reward point If it is useful
