Implementing UPDATE_ENTITYLocate this document in the navigation structure

Use UPDATE_ENTITY to update the Note, Lifecycle Status, Billing Status, and Delivery Status fields of the SalesOrders entity.

Procedure

  1. From the Class Builder screen for class ZCL_Z_EPM_RKT_DPC_EXT, scroll down to the SALESORDERS_UPDATE_ENTITY method, place the cursor in the row, and click Redefine.
  2. Implement the method with this code:
    method SALESORDERS_UPDATE_ENTITY.
    
        DATA: lv_id(10)            TYPE          N,
              ls_id                TYPE          bapi_epm_so_id.
        DATA: ls_headerdata        TYPE          bapi_epm_so_header,
              lt_return            TYPE TABLE OF bapiret2,

        lt_keys = io_tech_request_context->get_keys( ).
    
        READ TABLE lt_keys WITH KEY name = 'SO_ID'
          ASSIGNING <ls_key>.
    
        IF sy-subrc EQ 0.
          lv_id = <ls_key>-value.
        ENDIF.
    
    
        IF lv_id IS INITIAL.
          ls_message-msgid = 'SY'.
          ls_message-msgno = '002'.
          ls_message-attr1 = 'No Sales Order ID provided'.
          RAISE EXCEPTION TYPE /iwbep/cx_mgw_busi_exception
            EXPORTING
              textid = ls_message.
        ENDIF.
    
        io_data_provider->read_entry_data( IMPORTING es_data = ls_headerdata ).
    
        ls_id-so_id = lv_id.
    
        " EPM: Sales Order header data fields that can be updated
        " using the OData service
    
        ls_headerdatax-so_id = lv_id.
        ls_headerdatax-note = 'X'.
        ls_headerdatax-LIFECYCLE_STATUS = 'X'.
        ls_headerdatax-BILLING_STATUS = 'X'.
        ls_headerdatax-DELIVERY_STATUS = 'X'.
    
        CALL FUNCTION 'BAPI_EPM_SO_CHANGE'
          EXPORTING
            SO_ID               = ls_id
            SOHEADERDATA        = ls_headerdata
            SOHEADERDATAX       = ls_headerdatax
          TABLES
            RETURN              = lt_return
                  .
    
        IF lt_return IS NOT INITIAL.
    
          LOOP AT lt_return INTO ls_return.
    
            err_msg = ls_return-message .
    
          ENDLOOP.
    
          ls_message-msgid = 'SY'.

          ls_message-attr1 = err_msg.

            EXPORTING
              textid = ls_message.
    
        ENDIF.
    
        MOVE-CORRESPONDING ls_headerdata TO er_entity.
    
    endmethod. 
    

    The BAPI function BAPI_EPM_SO_CHANGE updates data using the passed in SO_ID key. The implementation defines four fields (Note, Lifecycle Status, Billing Status, and Delivery Status) that can be updated by using the ls_headerx structure. A successful UPDATE/PUT operation does not return updated data in the response body, which complies with the OData standard for a PUT operation, instead it returns an HTTP response code of 204, confirming a successful update operation.
