About BAPI ANF BADI

Question

Hi experts,
What is BAPI'S AND BADI'S? give me  information along with some example..

Answer 1

Hi,
Bapi is used to create the Database Entries :
Running BAPI directly hits the Database..for eg PO is created by running Tcode ME21n and the changes are reflected in the ReleVANT TABLES..
LIKE ekko AND ekpo so on ..
But running BAPI is direct way..when u pass all the header and item details..
Whereas BADi is provided in the SAP code just like Customer Exits..
to adjust the User Requirement .
BAdi is Object Oriented..
BAPI (Business Application Programming Interface) :
BAPIis an API method of a business object which intern is a RFC enabled Function Module.
Business Objects are the Objects which has business sence associated to it. Ex. Sales Orders, Purchase Orders etc.
The Properties of BAPI are:
Every BAPI name should start with letters 'BAPI'.
It is an API method of a Business Object.
it does not contain a internal COMMIT statement in the Function Module.
It does not contain "CALL TRANSACTION" statements.
BAPI do not raise 'EXCEPTIONS'.
a RETURN structure is defined as an interface parameter of a BAPI which is used to log all the errors, warnings and the successful processes tha are triggered in the course of execution of a BAPI.
A successful execution of a BAPI requires the data to be commited and this process of performing a COMMIT is achieved by calling the BAPI_TRANSACTION_COMMIT' explicitly if there are no errors logged in the RETURN structure.
There are two types of BAPI's: Instance Dependent & Instance Independent.
BAPI provides an access to the SAP system for external applications to have the business data processed in the form of web services. When BAPI's are used to post the data in SAP system these are used as Function Modules.

BADI
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects.
Badi’s allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like).
Business Add-Ins can be created at each level within such a system infrastructure
Some BADI can have multiple independent implementations which is much better for software deployment as several developers can implement the same BADI independently.
1} Identify the User Exit suitable for the requirement and that is available in the system:
Code SE18 is used to Identify the BADI available.
Look for the string 'CL_EXITHANDLER' in the standard program. This is a class which has a method 'GET_INSTANCE' which is used to trigger BADI's from the Standard Program. The interface parameter for this static method 'EXIT_NAME' is used to pass the BADI to the method.
Open Standard Program and do a global search 'CL_EXITHANDLER'.
SE18 > give the BADI name found through above search.
CUSTOMER_ADD_DATA > which has a method SAVE_DATA.
2} Implement the User Exit identified through above process.
T.Code SE19 is used to Implement BADI.
SE19 > give the implementation name > Give the Definition name as CUSTOMER_ADD_DATA and the Short Text.
