What is BAPI used for..For what purposes we aer using BAPI..

[ak_upadhyay]

Hi,

BAPIs

Definition

A Business Application Programming Interface (BAPI) is a precisely defined interface providing access to processes and data in business application systems such as R/3.

BAPIs of SAP Business Object Types

BAPIs are defined as API methods of SAP business object types. These business object types and their BAPIs are described and stored in the Business Object Repository (BOR). A BAPI is implemented as a function module, that is stored and described in the Function Builder.

BAPIs of SAP Interface Types

As of Release 4.5A BAPIs can also describe interfaces, implemented outside the R/3 System that can be called in external systems by R/3 Systems. These BAPIs are known as BAPIs used for outbound processing. The target system is determined for the BAPI call in the distribution model of Application Link Enabling (ALE).

BAPIs used for outbound processing are defined in the Business Object Repository (BOR) as API methods of SAP Interface Types. Functions implemented outside the R/3 System can be standardized and made available as BAPIs. For further information see BAPIs Used For Outbound Processing.

Integration

BAPIs can be called within the R/3 System from external application systems and other programs. BAPIs are the communication standard for business applications. BAPI interface technology forms the basis for the following developments:

Connecting:

New R/3 components, for example, Advanced Planner and Optimizer (APO) and Business Information Warehouse (BW).

Non-SAP software

Legacy systems

Isolating components within the R/3 System in the context of Business Framework

Distributed R/3 scenarios with asynchronous connections using Application Link Enabling (ALE)

Connecting R/3 Systems to the Internet using Internet Application Components (IACs)

PC programs as frontends to the R/3 System, for example, Visual Basic (Microsoft) or Visual Age for Java (IBM).

Workflow applications that extend beyond system boundaries

Customers' and partners' own developments

HI,

Purpose

To use a BAPI, you have to determine the information you have to forward to call the BAPI or function in your application program.

Prerequisites

You can find this information in the BAPI Explorer or in the BAPI Browser.

The BAPI Explorer is available as of Release 4.6A and replaces the BAPI Browser used in earlier releases. The BAPI Explorer uses up-to-date HTML control technology which requires SAPgui version 4.6A.

If you are using a SAPgui from an earlier release, the BAPI Browser is displayed instead of the BAPI Explorer.

Details of BAPIs of Business Object Types

The following information is required to use BAPIs of SAP business object types:

The import, export and import/export parameters of the BAPI

Standardized parameters supply the same or equivalent data and can therefore be used in different BAPIs. These parameters have the same name in all BAPIs and are implemented using the same guidelines. For further information see Standardized Parameters.

They key fields of the SAP business object type

The key fields of SAP business object types specify the identification structure with which client programs can uniquely access a specific instance of the object type. The key fields are required if the BAPI is using specific instances of an object type. BAPIs are divided into these categories:

- Instance-dependent BAPIs

Instance-dependent BAPIs use specific instances of an object type which the client application must specify in the key fields of the business object. An example of an instance-dependent BAPI is CompanyCode.GetDetail() and when used the client application must specify the company code ID, for example, GetSAPObject("CompanyCode","0001").

- Instance-independent BAPIs

Instance-independent BAPIs do not use specific instances of an object type. They usually return a list of object type instances in tables to the calling program. Instance-independent BAPIs are also called class methods. The BAPI CompanyCode.GetList(), which returns a list of company codes, is an example of an instance-independent BAPI.

Some instance-independent BAPIs generate object instances and report back information on the generated object instance to the calling application. An example of this type of BAPI is SalesOrder.CreateFromData(), which creates a customer order and reports back information to the calling program.

· The documentation on the business object type, the key fields, the BAPI and its parameters.

· The name of the function module, if the RFC calls are sent to the function module underlying the BAPI.

Once you have retrieved all the required information, you can use the BAPI in your application program.

Details of BAPIs of Interface Types

The following information is required to use BAPIs of SAP business object types:

The import, export and import/export parameters of the BAPI

The name of the function module that is to implement the interface

The documentation on the BAPI and its parameters.

Once you have retrieved all the necessary information, you can implement the interface and use the BAPI in your application program.

Process Flow

From the initial R/3 screen, choose Tools ® Business Framework ® BAPI Explorer or enter the transaction code BAPI in the SAPgui command field.

If you are using a SAPgui of Release 4.6A or later, the BAPI Explorer will be displayed. For more information about using the BAPI Explorer see BAPI Explorer.

If you are using a SAPgui in a release earlier than 4.6A, the BAPI Browser appears instead of the BAPI Explorer. For further information see BAPI Browser.

BAPI (Business Application Programming Interface) is 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.

to create a bapi:

STEP 1 - Define a structures for the BAPI

STEP 2 - Write Function Module

Important notes:

• Each BAPI must have its own function group.

• Under the attrbutes tab remember to select Processing Type Remote Enabled module, otherwise the function module cannot be invoked via RFC and used as a BAPI

• Import/Export parameters can only be BY VALUE for an RFC enabled function module

• We are only creating one BAPI in this example, but you can create related BAPIs in the same function pool, so they will be able to share global data.

STEP 3 - Create the API Method Using the BAPI WIZARD

The BAPI wizard is used toTo expose the remote function module as a BAPI. The wizard will generate some additional code, so the function module is a valid method of the BOR. This allows the BAPi to be called as a workflow method in addition to be called by an outside program.

Note: Each functionmodule corresponds to a method in the BOR

Go to the Busines Object Builder SWO1.

Supertype: Not relevant because we are creating our object from scratch

Program. This is the name of the program where the wizard generates code for the Object type, NOT the function module we craeted earlier. The program name must not be the name of an existing program.

STEP 4 - Final steps

When the Business object has been checked and the documentation created, the follwing steps must be carried out:

• Release the BAPI function module (in the Function Builder).

• Release the business object type (in the BOR ObjectType -> Change release status to -> Implemented ).

• Release the BAPI as a method in the BOR (Release the methods you have created - Set the cursor on the method then Edit .

HI,

BAPI is Business API. It is used in mySAP to achieve business related functionalities. It is a remote enabled function module which is provided by SAP. The transaction code for BAPI is BAPI and the BAPI repository can be accessed using the t-code swo3. Business Application Programming Interfaces (BAPIs) enable access to SAP functions across formal, stable and dialog-free interfaces. These interfaces can be used by external applications developed by customers and complementary software partners as well as by other SAP applications. BAPIs are defined as API methods of SAP Business Object Types [Ext.]. These object types are used within the Business Framework to enable object-based communication between components. Business objects and their BAPIs enable object orientation to be used in central information processing in companies. For example, existing functions and data can be reused, trouble-free technical interoperability can be achieved, and non-SAP components can be implemented. Applications can use BAPIs to directly access the application layer of the R/3 System and, as clients, applications can use the business logic of the R/3 System. BAPIs provide the client with an object-oriented view of the application objects, without needing to know the implementation details. BAPIs are always developed by defining scenarios. These scenarios are used to map and implement system-wide business processes.

Thanks&Regards,

Phani,
