Hi
what is BAPI?
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

Bdc to Bapi
The steps to be followed are :
1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
[for VA01 use BAPI_SALESORDER_CREATEFROMDAT2]
2. Create a Z program and call the BAPi (same as a Funtion module call).
2. Now, if you see this BAPi, it has
-> Importing structures.
eg: SALESDOCUMENT: this will take the Sales order header data as input.
-> Tables parameters:
eg: ORDER_ITEM_IN: this will take the line item data as input.
Note :
Only specify fields that should be changed
Select these fields by entering an X in the checkboxes
Enter a U in the UPDATEFLAG field
Always specify key fields when changing the data, including in the checkboxes
The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
Maintain quantities and dates in the schedule line data
Possible UPDATEFLAGS:
U = change
D = delete
I = add
Example
1. Delete the whole order
2. Delete order items
3. Change the order
4. Change the configuration
Notes
1. Minimum entry:
You must enter the order number in the SALESDOCUMENT structure.
You must always enter key fields for changes.
You must always specify the update indicator in the ORDER_HEADER_INX.
2. Commit control:
The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
For further details... refer to the Function Module documentation for the BAPi.
Bapi to VB(Visual Basic)
Long back I had used the following flow structure to acheive the same.
Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
You need to have com4abap.exe
If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.
else refer OSS note 419822 for installation of com4abap
after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
for setting up com4abap and rfc destination please refer to the documentation for com4abap.
Invoke NEW DCOM session
call function 'BEGIN_COM_SESSION'
exporting
service_dest = service_dest "(this will be a RFC destination created in SM59)
importing
worker_dest = worker_dest
exceptions
connect_to_dcom_service_failed = 1
connect_to_dcom_worker_failed = 2
others = 3.
call function 'create_com_instance' destination worker_dest
exporting
clsid = g_c_clsid

Hi..
BAPIs are internally Remote Enabled Function modules.
But these BAPIs are created as Methods of the Business objects in Business object builder Tcode SWO1.
So we can call a BAPI from an External system (SAP or NON SAP)
and We can call a BAPI internally like a Function module.
<b>Reward if Helpful.</b>
2007 Aug 07 7:47 AM
Hi,
BAPI is kind of normal Function module wher the data represents in business oriented unlike in normal function module where we use the login understand with in SAP.

<b>The Business Application Programming Interfaces (BAPI) allow object-oriented access to the SAP system through methods for the business object types. Together with the business object types, BAPIs define and document the interface standard at the business level.</b>
BAPIs (Business Application Programming Interfaces) are the standard SAP interfaces. They play an important role in the technical integration and in the exchange of business data between SAP components, and between SAP and non-SAP components. BAPIs enable you to integrate these components and are therefore an important part of developing integration scenarios where multiple components are connected to each other, either on a local network or on the Internet.
BAPIs allow integration at the business level, not the technical level. This provides for greater stability of the linkage and independence from the underlying communication technology.
Object-oriented technologies have become standard for communication between different software products. For this reason SAP has introduced business object types that structure the data and processes according to business criteria. Business object types are used to break the SAP system down into smaller, disjunctive units, improving its structure and reducing its complexity.
BAPIs are defined as methods for the business object types. As a result, both the object-oriented structures in SAP Systems and the opportunity for object-oriented access are offered. These object-oriented interfaces allow other components to directly access the application layer of an SAP system without having to know the specific implementation details.
The introduction of business object types and their BAPIs enable object orientation to be used in central information processing in companies. For example, you can reuse existing functions and data, achieve trouble-free technical interoperability, and implement non-SAP components.
When implementing BAPIs, you should pursue the goal of avoiding the disadvantages of the "postcard effect" associated with conventional interfaces: No separation between contents and transport. In the case of a postcard, the text is written on a card that also serves as the information medium. If the information medium changes, then the receiver has to read the text in a different way. As a result, changes to the interface affect the type of access.
BAPIs, in contrast, clearly separate the business contents from the underlying communication technology. This procedure can be compared to a letter in an envelope: It is easy to put a letter in a new envelope, just like it is easy to apply new and/or different communication technologies like COM/DCOM, the CORBA standard, or new Internet standards. The envelope itself is irrelevant to understanding the contents of the letter. In this example, the BAPIs correspond to the letter, meaning they are independent of the programming language and communication mechanisms used.
Using BAPIs results in the following benefits:
BAPIs represent well-defined, internally consistent units that always represent business facts and leave a consistent database state behind.
The business contents can be standardized, since BAPIs not only allow the integration of the SAP system and other software components at a technical level, but also at the business level.
BAPIs have become a communication standard between business systems. Access is possible through object-oriented interface technologies (such as COM/DCOM from Microsoft). The SAP business objects conform to the guidelines of the OAG (Object Application Group), and meet the CORBA standard from the OMG (Object Management Group).
Stability and compatibility
Once SAP has released a BAPI, its interface definitions and parameters will remain stable in the long term, which means application programs will not be affected by changes to the underlying SAP software or data. If upward-compatible enhancements are made to the BAPIs, the stability of the existing applications is not affected.
Openness
BAPIs can be accessed from any widespread development platform.
