Business add-ins are enhancements to the standard version of the system.

Business Add-In is a new SAP enhancement technique based on ABAP Objects.

They can be inserted into the SAP system based on specific user requirements.

Each Business Add-In has:

u2022 at least one Business Add-In definition

u2022 a Business Add-In interface

u2022 a Business Add-In class that implements the interface

In order to enhance a program, a Business Add-In must first be defined

Subsequently two classes are automatically generated:

u2022 An interface with u2018IF_EX_u2019 inserted between the first and second characters of the BADI name.

u2022 An adapter class with u2018CL_EX_u2019 inserted between the first and second characters of the BADI name.

The Application developer creates an interface for this Add-In.

There are multiple ways of searching for BADI.

u2022 Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE

u2022 Finding BADI Using SQL Trace (TCODE-ST05).

u2022 Finding BADI Using Repository Information System (TCODE- SE84).

1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for u2018CL_EXITHANDLER=>GET_INSTANCEu2019.

Make sure the radio button u201CIn main programu201D is checked. A list of all the programs with call to the BADIu2019s will be listed.

The export parameter u2018EXIT_NAMEu2019 for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter u2018INSTANCEu2019 will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.

2. Start transaction ST05 (Performance Analysis).

Set flag field "Buffer trace"

Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)

Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.

Push the button "Deactivate Trace".

Push the button "Display Trace".

The popup screen "Set Restrictions for Displaying Trace" appears.

Now, filter the trace on Objects:

u2022 V_EXT_IMP

u2022 V_EXT_ACT

Push button "Multiple selections" button behind field Objects

Fill: V_EXT_IMP and V_EXT_ACT

All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.

So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA

3. Go to u201CMaintain Transactionu201D (TCODE- SE93).

Enter the Transaction VD02 for which you want to find BADI.

Click on the Display push buttons.

Get the Package Name. (Package VS in this case)

Go to TCode: SE84->Enhancements->Business Add-inns->Definition

Enter the Package Name and Execute.

Here you get a list of all the Enhancement BADIu2019s for the given package MB.

What are BAdIs?

• is an anticipated point of extension – these points act like sockets and exist in the original source code

• based on ABAP Objects. BAdI defines an interface that can be implemented by BAdI-implementations that are transport objects of their own

• Important! There are 2 roles: Enhancement Option-provider & Implementer.

• In the above context, Enhancement Implementation can be done only if option (hook) is provided by the Option-provider. In simple words there are no implicit BAdIs.

Note: In the following slides, Definitions are created so as to understand the method of BAdI definition & for example purpose. As stated above this is the role of Enhancement Option-Provider.

Classic BAdIs already exist since SAP Release 4.6

BAdIs have been Re-implemented in ECC7.0 under the new Enhancement Framework & Switch Framework

Classic BAdIs

• To understand what a powerful pattern a BAdI is, we will now define & then implement a BAdI

BADI Class is created automatically.

The various options are described below in detail:

1. Enhanceable: Enhanceability of filter types can only be specified for filter-dependent BADI definitions under very special conditions. For example, the domain belonging to the filter type must be linked with a value table that is of the type E or G. A BADI implementation can then be created in one step by creating a new filter value that is automatically entered into the value table at save and also copied into the transport order of the BADI implementation. In addition, it is also possible to create a new filter value and, at the same time, a BADI implementation with the same name. Naturally, you can also specify existing filter values.

You should select this feature if there is a prerequisite that a new filter value is created together with a new BADI implementation - that is, that BADI implementations are not created solely with existing filter values, although this, too, is possible.

2. Multiple-Use

3. Filter-Dependent

Instance Methods can access all of the attributes of a class and can trigger all events of a class. Static Methods can only access static attributes and static events.
