Business Transaction Event - RWBAPI01 - For Accounting Document Interface

Link to Content's target Space :

http://wiki.sdn.sap.com/wiki/display/ABAP/BTE+-+Business+Transaction+Event

Applies to:

SAP 4.7x and above.

Summary

While Creating the Accounting document through BAPI - BAPI_ACC_DOCUMENT_POST posting keys are determined automatically based on the configuration.  Since this BAPI doesn't have any structure field to pass the posting key, posting keys are picked up automatically based on the document type passed in BAPI header structure.
This document narrates how to change the default posting key while creating the Accounting document using the above BAPI.  This document also explains the steps involved in implementing a Business Transaction Event.

Posting of Accounting Document Using BAPI - BAPI_ACC_Document Post

Scenario

Create the accounting document for Customer advance payment against Net-banking transaction.  Document is to be created with the accounting document type (DZ-Customer Payment).  Based on the Configuration, Customer line item is posted against the posting key 01(Invoice-Debit) and GL Account line item is posted against the posting key 50(GL-Credit).

Since the FI documents of customer payment and Advance payment is to be separated, Customer line item of above entries are to be posted with posting key 04 (Other Receivables - Debit) and GL Account line item to be posted with posting key 50 (GL - Credit)

Additional Structure for BAPI

For passing the additional data related to posting keys, Structure EXTENSION1 is to be filled with the required data.  Business Transaction Event used for changing the Posting key will be executed only when the record(s) are available in this structure.  See the Call to BTE in line number 59 of BAPI.

Implementing Business Transaction Event - RWBAPI01

Code for BTE Function Module

Step 1: Create a New function group using transaction code SE80
Step 2: Copy the standard function module of BTE "SAMPLE_INTERFACE_RWBAPI01" to a Z Function module, say "ZSAMPLE_INTERFACE_RWBAPI01"
Step 3: Add Following Code into the new function module and activate

Error rendering macro 'code': Invalid value specified for parameter 'lang'
FUNCTION zsample_interface_rwbapi01.
 *"--------------------------------------------------------------------
 ""Local Interface:
 *"  TABLES

    READ TABLE it_accit WITH KEY posnr = wa_extension-field1(10).
    IF sy-subrc EQ 0.
        it_accit-bschl = wa_extension-field1+10(2).
        MODIFY it_accit INDEX sy-tabix.
    ENDIF.
  ENDLOOP.
 ENDFUNCTION.


 

Configuration

Step 1: Go To Transaction code FIBF

Step 2: Add Customer Product. Use Menu Option :  Settings -> Products -> ...of a Customer
Step 3: Save the Product.

Step 4: Create a Link between BTE and Product created in Step2.  Use the menu option :  Settings -> Process Modules -> ... of a customer
Step 5: Save the Link.

Summary

When the BAPI is executed, Code written in the BTE - function module will be executed and the posting key of related line item will be changed before posting the documents.

  1. Dear Vinod,

    Thanks for this useful information.

    I tried the same but the BTE Function Module is not getting triggered while call the BAPI_ACC_DOCUMENT_POST.

    Need help on that.

    Regards

  2. Former Member

    Very Good Document.

  3. Former Member

    Its useful document

    @Deepak Batra,

    Are you able to resolve this issue.  BTE Function Module is not getting triggered while call the BAPI_ACC_DOCUMENT_POST.

    I am also facing the same issue.

     

     

  5. Hello,

    In order to trigger this BTE, you need to pass a non-empty internal table extension1[] to the BAPI, as the BAPI code is doing a check if this table is empty, before calling the BTE.

    Regards

    Hi, Thanks for your reply. Still not able to trigger BTE. passed  Extension1 also now. Below is my BAPI call. Extension 1 as empty table.
