BAPI step by step procedure

STEP 1 - Define Structure For The BAPI

STEP 2 - Write Function Module

STEP 3 - Create the API Method Using The BAPI WIZARD

STEP 4 – Final Steps

Step 1 :

Define a Structure for BAPI

In this step structures for the parameters and tables of the

function module used for the BAPI are defined.

USE TCODE : SE11 then Data type -> Structure

Define the structure Name : Ex: ZVEND

Important note: You will have to define a structure for

every parameter in the BAPI. You cannot use the same

structures used in existing applications because BAPI

structures are frozen when BAPIs are released and then

there are restrictions on changing them.

Step 2 :

Write Function Module

Each BAPI must have its own function group.

Under the attributes 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

Step 3 : Create the API Method Using

The BAPI WIZARD

BAPI wizard is used to expose the remote function module as a BAPI

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.

Each function module corresponds to a method in the BOR

Go to the Business Object Builder SWO1.

You can either create the new Object type as a subtype of an existing business

object or create a new business object from scratch..

Create new BAPI Object

USE TCODE

SWO1

Supertype not

required as we are

creating a new Object

for Cross

Apps

Create new BAPI Object

Note that when you create the business object a standard

interface, an attribute ObjectType and the methods

ExistenceCheck and Display are automatically generated.

These cannot be changed !

Adding API method

Implementing BAPI Object

Select the BAPI object

Implementing BAPI Object

Change release status To implemented

Releasing BAPI Object

Change release status To released

Implementing API Method

Select the API Method

Implementing API Method

Change release status To implemented

Releasing API Method

Change release status To released

Generating API Method

At last you can see your bapi in BAPI transaction....

u can check the below the material also

what is BAPI?

BAPI stands for Business API(Application Program Interface).

I have answered this question before..

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.

Example Code

U need to give the step_nr, item_nr, cond_count and cond_type so the correct conditon will be updated. If no condition exists for the given parameters, a new condition will be created.

U can find these parameters for a particular condition type in table KONV.

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

typelib = g_c_typelib

importing

instid = g_f_oid

exceptions

communication_failure = 1 message g_f_msg

system_failure = 2 message g_f_msg

invalid_instance_id = 3

others = 4.

call function 'com_invoke' destination worker_dest

exporting

%instid = g_f_oid

%method = 'UpdatePDF'

sntemp = g_v_const_filent

snsysid = sy-sysid

snflag = 'N'

tables

rssaptable = g_t_pdfdetail1

%return = g_t_pdfdetail1 "t_test

exceptions

communication_failure = 1 message g_f_msg

system_failure = 2 message g_f_msg

invalid_instance_id = 3

others = 4.

then close the com session , using

FM delete_com_instance

FM END_COM_SESSION

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.
