Creating a BAPI

Go to transaction sw01 (that is Tools->Business Framework -> BAPI Development ->Business Object builder ) .

Select the business object ( generally of type BUS nnnn ) , according to the functional requirement for which the BAPI is being created.

Open the business object in change mode. Then Select Utilities ->API Methods ->Add method.

Then enter the name of the function module and select Continue.

Creating a BAPI cont’d…

In the next dialog box, following information needs to be specified :

Method : Suggest an appropriate name for the method,

Texts : Enter description for the BAPI,

Radio buttons : Dialog, Synchronous, Instance-independent . BAPI ‘s are usually implemented synchronously.

Now, select Next step.

To create the method select Yes in the next dialog box.

After the program has been generated and executed, check the program in the method just created.

Thus , a BAPI is created.

Example :-

Initially a remote function module , called ZTEST_BAPI is created ( which has ABAP code to create a sales order)

Then a BAPI is created in the business object ZTEST12 as below :

Next step :

And thus a BAPI is created.

Testing the BAPI :-

You can test the BAPI by testing the individual method of the Business Object in the Business Object Builder.

( or one can use the transaction ‘swud’ to test the method ) .

Releasing and freezing the BAPI :-

-To release the BAPI , first release the function module ( using transaction se37 ) .

-Set the status of the method to 'released' in the Business Object Builder .

( using transaction swo1 – Edit-> change status-> released. )

Use of BAPI in Custom programs

Step 1: First step is to identify the application area. Then go to the transaction code BAPI and obtain the corresponding BAPI.

Eg : if your dealing with a sales order , in the BAPI explorer , go to sales and distribution-> sales->sales order.

Step 2: Refer to the documentation of the method to know how to use the BAPI.

Eg : In order to create a sales order, select the BAPI CreateFromDat2. (BAPI_SALESORDER_CREATEFROMDAT1).

Step 3: Simulate the desired output using SE37 transaction. Do sample testing with the function module found. SAP does not specify flag population part to control the update. That you can achieve by some trial run of the function module.

Example :

Call function ‘BAPI_SALESORDER_CREATEFROMDAT1’

EXPORTING

Order_header_in = s_order_header

IMPORTING

Salesdocument = w_sales_docno

Return = s_return

TABLES

Order_items_in = t_order_item

Order_partners = t_order_partner

Order_item_out = t_order_item_out.

Here, in the ‘s_order_header’ structure we fill all the header data of the sales order to be created.

Eg:- s_order_header-sales_org = ‘FR03’,

s_order_header_distr_chan = ’01’. Etc..

In t_order_item table we fill all the item data of the sales order, eg. T_order_item-material = ‘M13321’,

T_order_item-plant = ‘0033’.

append t_order_item.

Similarly we fill, t_order_item_out,t_order_partner tables.

In the structure s_return, we will get the return messages from the BAPI , eg. ‘Sales order created successfully’ or

‘Error in item ‘020’’.

If the BAPI is successful, the number of the sales order created will be returned in the field, ‘w_sales_docno’.

Once , the BAPI is successful, to commit the changes to the database, we must use the function module,

‘BAPI_TRANSACTION_COMMIT’.

CALL FUNCTION ‘BAPI_TRANSACTION_COMMIT’

EXPORTING

wait = ‘X’.

hus, we can create a sales order, using the appropriate BAPI, and similarly, we can use BAPI’s for many other applications.

if its useful plz reward me

thanx
