HI,

I HAVE CREATED ONE BAPI .

This BAPI reads system status for a production order from table JEST and system status text from table TJ02T.

Ashok,

BADI creation

STEP 1 - Define a structures for the BAPI

STEP 2 - Write Function Module

STEP 3 - Create the API Method Using the BAPI 5 WIZARD

STEP 4 - Final steps

This BAPI reads system status for a production order from table JEST and system status

text fro table TJ02T

Name ZGetOrderStatus

Function group ZBAPISTATUS

Function module: Z_BAPI_GET_ORDER_STATUS

Import parameters: ORDER_STATUS_IMPORT type

ZBAPI_ORDER_STATUS_IMPORT: AUFNR Order number (Keyfield)

SPRAS Language ExcludeInactive - Checkbox -

Exclude inactive status

Tables T_BAPISTAT type ZBAPISTAT:

OBJNR like JEST-OBJNR

STAT like JEST-STAT

INACT like JEST-INACT

TXT04 like TJ02T-TXT04

TXT30 likeTJ02T-TXT30

Export parameters RETURN like BAPIRETURN

STEP 1 - Define a structures for the BAPI

In this step structures for the parameters and tables of the function module used for

the BAPI are defined.

Use Data type -> Structure

Define the following structures:

ZBAPI_ORDER_STATUS_IMPORT which contains the following fields:

ORDERID Order number (Keyfield)

SPRAS Language

ExcludeInactive - Checkbox - Exclude inactive status

ZBAPISTAT:

OBJNR like JEST-OBJNR

STAT like JEST-STAT

INACT like JEST-INACT

TXT04 like TJ02T-TXT04

TXT30 likeTJ02T-TXT30

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.

ZBAPI_ORDER_STATUS_IMPORT

ZBAPI_ORDER_S

TATUS_IMPORT

ZBAPISTAT

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.

attributes

Import Parameters

Export Parameters

Tables

Code

Notes:

The subroutine SET_RETURN_MESSAGE is a standard routine used for BAPIs that use the BAPIRETURN structure

In form Z_BAPI_GET_ORDER_SYSTEM_STATUS there is a test IF 1 = 2. If the test is true a mesage is displayed. The condition will obviously never be true, and we will never want to display a message in a BAPI. The reason why it

is included is, that it create a reference for the message, so that the WHERE USED funstionallity can be used for the message. This is the SAP standard way to handle it, copied from the Company Code GetList BAPI.

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.

You can either create the new Object type as a subtype of an existing business object or create a new business object from scratch. In

this example it would be obvious to create the Object type as a subtype of BUS2005 Production order. However, to illustrate how to

create a new Object type from scratch, we will do this.

In the Object/Interface type field write the name of the new Business Object: ZORDERSTAT. Press enter and fill in the additional fields

necessary to create the object type.

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 existinbg program.

Press enter and create the new business 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 !

The next step is to add the Z_BAPI_GET_ORDER_STATUS method to the business object. Select Utillities -> API methods -> Add method and write the name of the

functionmodule in the dialogbox. Next the dialogbox show below will be shown. This is the start screen of the BAPI wizard. Proceed with wizard by pressing the button.

After you have finished the wizard, tyou will notice that the ZGetOrderStatus has been added to

the business object:

You can doubleclick on the method to see its properties. To use the business object you must change the Object type status to Implemented. Use menu Edit->Change releases

status->Object type->To implemented. No you can test thge object (Press F8).

Note that the BAPI wizard has added a wrapper class for the function module so it can be sued as method in the business object. Choose menu Goto->Program to display the

program:

Implementation of object type ZORDERSTAT *****

INCLUDE <OBJECT>.

BEGIN_DATA OBJECT. " Do not change.. DATA is generated

only private members may be inserted into structure private

DATA:

" begin of private,

" to declare private attributes remove comments and

" insert private attributes here ...

" end of private,

KEY LIKE SWOTOBJID-OBJKEY.

END_DATA OBJECT. " Do not change.. DATA is generated

BEGIN_METHOD ZGETORDERSTATUS CHANGING CONTAINER.

DATA:

BAPIORDERSTATUSIMPORT LIKE ZBAPI_ORDER_STATUS_IMPORT,

RETURN LIKE BAPIRETURN,

TBAPISTAT LIKE ZBAPISTAT OCCURS 0.

SWC_GET_ELEMENT CONTAINER 'BapiOrderStatusImport'

BAPIORDERSTATUSIMPORT.

SWC_GET_TABLE CONTAINER 'TBapistat' TBAPISTAT.

CALL FUNCTION 'Z_BAPI_GET_ORDER_STATUS'

EXPORTING

BAPI_ORDER_STATUS_IMPORT = BAPIORDERSTATUSIMPORT

IMPORTING

RETURN = RETURN

TABLES

T_BAPISTAT = TBAPISTAT

EXCEPTIONS

OTHERS = 01.

CASE SY-SUBRC.

WHEN 0. " OK

WHEN OTHERS. " to be implemented

ENDCASE.

SWC_SET_ELEMENT CONTAINER 'Return' RETURN.

SWC_SET_TABLE CONTAINER 'TBapistat' TBAPISTAT.

END_METHOD.

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 has created - Set the cursor on the

method then

Edit -> Change release status -> Object type component -> To released )

For potential write BAPIs: Release the IDoc and its segments

You can now display the BAPI in the BAPI Explorer:

Hi,

You can browse all the BAPI's in a system from the transaction BAPI, there you can naviagte to your BAPI and then execute it.

Former Member — Tue, 26 Jun 2007 06:32:25 GMT

Hi Ashok Kumar,

Hope if you have executed SW01 then your BAPI API registered in BAPI transaction.

Check BAPI trancation. Whether your BAPI is appearing in the list.

call your BAPI in the program BAPI_GET_ORDER_SYSTEM_STATUS

or executre your function directly from SW01 by clicking on execute button.

Reward if useful!
