Extending BAPI Function Module 'BAPI_ALM_ORDER_MAINTAIN'

[Former Member]

This document helps how to extend the BAPI function module 'BAPI_ALM_ORDER_MAINTAIN' for Z fields.

In order to extend the BAPI, we should have EXTENSION_IN table which is type of BAPIPAREX.

Please follow the below steps to extend the BAPI.

1. In AUFK table, we have custom include with name 'CI_AUFK'. So add the Z field ZZLEG_PM_ORD in structure CI_AUFK and activate it. Now we have a custom field ZZLEG_PM_ORD in standard table AUFK.

2. Create a append structure with the Z field ZZLEG_PM_ORD which should be type of BAPIUPDATE and append to the BAPI structure ‘IBAPI_CAUFVD_UPDATE’.

3. Now we should implement the BADI 'IBAPI_ALM_ORD_MODIFY' to push the custom field ZZLEG_PM_ORD value to table AUFK. Use the method IF_EX_IBAPI_ALM_ORD_MODIFY~MODIFY_INPUT_DATA to pass the Z field ZZLEG_PM_ORD value from EXTENSION_IN table to Order header data.

Please use the below logic for updating order header data.

Read the table CT_HEADER_INT into LS_HEADER_INT index 1. Pass the value from EXTENSION_IN-VALUEPART1+0(12) to LS_HEADER_INT-ZZLEG_PM_ORD and modify the table CT_HEADER_INT.

4. Once we have completed the above steps, while calling the BAPI function module 'BAPI_ALM_ORDER_MAINTAIN', we should populate the EXTENSION_IN table and pass to BAPI as below.

   The EXTENSION_IN structure has two fields with name STRUCTURE and VALUEPART1. So pass the STRUCTURE name as

   'BAPI_TE_AUFK' and VALUEPART1 should be the custom field value.

   Now pass the LT_EXTENSION_IN to the BAPI function module.

    CALL FUNCTION 'BAPI_ALM_ORDER_MAINTAIN'
    TABLES
      IT_METHODS         = PT_METHOD_BAPI
      IT_HEADER            = PT_HEADER_BAPI
      IT_HEADER_UP      = LT_HEADER_BAPIX
      IT_OPERATION      = PT_OPERATION_BAPI
      IT_COMPONENT    = PT_COMPONENT_BAPI
      IT_TEXT                 = PT_TEXT_BAPI
      IT_TEXT_LINES      = PT_TEXT_LINES_BAPI
      RETURN                = PT_RETURN
      EXTENSION_IN      = P_LT_EXTENSION_IN
      ET_NUMBERS      = LT_ORD_NUM.
