OData:无法创建有效的get_entity方法(RFC nore ABAP)

时间:2016-09-29 11:09:04

标签: odata sap abap rfc netweaver

我已经创建了一个用于测试目的的简单表,并希望在get_entity中实现SEGW方法。

我有一个获取两个密钥并返回匹配条目的RFC。

SELECT SINGLE * FROM ZORDER
  INTO ORDERRETURN
  WHERE ORDERADVENCO    = ORDERADVENCOINPUT AND
        POSITIONADVENCO = POSITIONADVENCOINPUT.

我尝试使用/sap/opu/odata/sap/ZORDER_RFC_SRV/OrderSet(Orderadvencoinput='10100', Positionadvencoinput='10')进行调用,但收到错误400: Bad request

我的元数据返回以下内容:

我也试图自己编写方法:

  DATA:  lt_keys TYPE /iwbep/t_mgw_tech_pairs,
         ls_key TYPE /IWBEP/S_MGW_TECH_PAIR,
         lv_ORDERADVENCO   TYPE zorder-ORDERADVENCO,
         lv_POSITIONADVENCO  TYPE zorder-POSITIONADVENCO,
         ls_order TYPE  zorder.
         lt_keys = io_tech_request_context->get_keys( ).
  READ TABLE lt_keys with key name = 'Orderadvenco' into ls_key.
  lv_ORDERADVENCO = ls_key-value.
  READ TABLE lt_keys with key name = 'Positionadvenco' into ls_key.
  lv_POSITIONADVENCO = ls_key-value.
  SELECT SINGLE * FROM ZORDER
                  INTO ls_order
                  WHERE ORDERADVENCO    = lv_ORDERADVENCO and 
                        POSITIONADVENCO = lv_POSITIONADVENCO.
  IF sy-subrc = 0.
    er_entity-ORDERADVENCO = ls_order-ORDERADVENCO.
  ENDIF.
endmethod.

但在这种情况下,lv_ORDERADVENCOlv_POSITIONADVENCO似乎没有任何价值。这是sy-subrc = 4,因此失败。

更新: 所以我现在打电话给:

/ SAP / OPU /的OData / SAP / ZORDER_RFC_SRV_01 / OrderSet(Orderadvenco =&#39; 10100&#39;,Positionadvenco =&#39; 10&#39)

...但得到错误:

<code>/IWBEP/CX_MGW_BUSI_EXCEPTION</code>

<message>Resource not found for segment 'Order'</message>

我的Orderadvenco和Positionadvenco似乎也没有抓住我试图传递的价值......

enter image description here

PS:我也实现了

/ SAP / OPU /的OData / SAP / ZORDER_SRV / OrderSet

工作正常,但有趣的部分是它调用:

<id>http://vhcala4hci.wdf.sap.corp:50000/sap/opu/odata/SAP/ZORDER_SRV/OrderSet(Orderadvenco='10100',Positionadvenco='10')</id>

但是当我尝试调用该链接时,它失败并出现与上面相同的错误。

答案 0 :(得分:1)

查看$元数据文件会显示错误。您的实体类型&#39;订单&#39;有两个关键属性:&#39; Orderadvencoinput&#39;和&#39; Positionadvencoinput&#39;。当试图访问/ sap / opu / odata / sap / ZORDER_RFC_SRV / OrderSet(Orderadvencoinput =&#39; 10100&#39;,Positionadvencoinput =&#39; 10&#39;)表IT_KEY_TAB(或在您的情况下为lt_keys)被填充用这两把钥匙。但是,您尝试从表格中读取的是lt_keys,其中NAME字段填充为&#39; Orderadvenco&#39;和&#39; Positionadvenco&#39;。因此,两个READ TABLES将始终失败,因此ls_key仍然是初始的,因此lv_ORDERADVENCO和lv_POSITIONADVENCO是初始的。因此SELECT将失败并且sy-subrc = 4.网关常见的事情是抛出400 HTTP代码,因为请求的资源OrderSet(Orderadvencoinput =&#39; 10100&#39;,Positionadvencoinput =&#39; 10& #39;)没有填写(er_entity再次初始化)

您应该做的是将$ metadata中的确切属性名称放入READ TABLE语句中。

答案 1 :(得分:0)

好的问题是,尽管有电话:

OrderSet(Orderadvenco='10100',Positionadvenco='10')

lt_keys 包含:

  1. ORDERADVENCO 10100

  2. POSITIONADVENCO 10

  3. 所以我不得不改变:

    READ TABLE lt_keys with key name = 'Orderadvenco' into ls_key.
    READ TABLE lt_keys with key name = 'Positionadvenco' into ls_key.
    

    为:

    READ TABLE lt_keys with key name = 'ORDERADVENCO' into ls_key.
    READ TABLE lt_keys with key name = 'POSITIONADVENCO' into ls_key.
    

    其他错误:

    OrderSet(Orderadvenco =&#39; 10100&#39;,Positionadvenco =&#39; 10&#39;) - 我必须删除空间。

    谢谢@mash
