    Hello Chandu

    You may have BAPI_SALESORDER_CREATEFROMDAT2 available yet I would recommend to use the underlying RFC-enabled SD_SALESDOCUMENT_CREATE.

    Regards

    Uwe

    VA01:

    BAPI_SALESORDER_CREATEFROMDAT1

    BAPI_SALESORDER_CREATEFROMDAT2

    steps for bapi creation

    STEP 1 - Define a structures for the BAPI

    In this step a 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:

    STEP 2 - Write Function Module

    Important notes:

    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

    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.

    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 message 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 functionality can be used for the message. This is the SAP standard way to handle it, copied from the Company Code GetList BAPI.

    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 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 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. 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 created earlier. The program name must not be the name of an existing 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 Utilities -> API methods -> Add method and write the name of the function module in the dialog box. Next the dialog ox 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, you will notice that the ZGetOrderStatus has been added to the business object:

    You can double-click 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 the 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 stepsWhen the Business object has been checked and the documentation created, the following 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:
