FetchXML视图包含嵌套链接实体的属性

Question

我希望有一个视图显示来自3个实体的属性:
统计信息具有查找帐户和帐户具有查找地址.

视图是关于统计的,我想要来自所有3个实体的属性; 这有可能吗？

问题出在GridXML上.
我想在GridXML中包含属性wl_city.

这是带有链接实体的FetchXML:

<fetchxml>
  <fetch version="1.0" output-format="xml-platform" mapping="logical">
    <entity name="sb_statistics">
      <order attribute="sb_amount" descending="false" />
      <!-- It is easy to get these into the GridXML -->
      <attribute name="sb_debtor" />
      <attribute name="sb_date" />
      <attribute name="sb_amount" />
      <link-entity name="account" from="accountid" to="sb_debtor" 
       alias="relatedAccount" link-type="outer">
        <!-- It is possible to get this into the GridXML
             by using the link-entity alias: relatedAccount.wl_towncity -->
        <attribute name="wl_towncity" />
        <link-entity name="wl_postalcode" from="wl_postalcodeid" 
          to="wl_postaltowncity" alias="relatedAddress" link-type="outer">
          <!-- I have trouble getting this attribute into the GridXML -->
          <attribute name="wl_city" />
        </link-entity>
      </link-entity>
      <attribute name="sb_statisticsid" />
    </entity>
  </fetch>
</fetchxml>

当我在下面更改GridXML时,在打开视图时会显示此错误:
"要使用此保存的查询,您必须删除引用已删除或不可搜索项目的条件和列"

  <layoutxml>
    <grid name="resultset" object="10008" jump="sb_name" select="1" preview="1" 
     icon="1">
      <row name="result" id="sb_statisticsid" multiobjectidfield="1">
        <cell name="sb_amount" width="100" />
        <cell name="sb_date" width="100" />
        <cell name="sb_debtor" width="100" />
        <cell name="relatedAccount.relatedAddress.wl_city" width="100" />
      </row>
    </grid>
  </layoutxml>

打开视图时,下面的GridXML显示此错误:
" 意外错误发生错误".

  <layoutxml>
    <grid name="resultset" object="10008" jump="sb_name" select="1" preview="1" 
     icon="1">
      <row name="result" id="sb_statisticsid" multiobjectidfield="1">
        <cell name="sb_amount" width="100" />
        <cell name="sb_date" width="100" />
        <cell name="sb_debtor" width="100" />
        <cell name="relatedAddress.wl_city" width="100" />
      </row>
    </grid>
  </layoutxml>

下面的GridXML导致在打开视图时显示此错误:
"要使用此保存的视图,您必须删除引用已删除或不可搜索列的条件和列".

  <layoutxml>
    <grid name="resultset" object="10008" jump="sb_name" select="1" preview="1" 
     icon="1">
      <row name="result" id="sb_statisticsid" multiobjectidfield="1">
        <cell name="sb_amount" width="100" />
        <cell name="sb_date" width="100" />
        <cell name="sb_debtor" width="100" />
        <cell name="wl_city" width="100" />
      </row>
    </grid>
  </layoutxml>

此保存的查询有效,但它仅包含主实体和第一个链接实体的属性.

<savedquery>
  <IsCustomizable>1</IsCustomizable>
  <CanBeDeleted>0</CanBeDeleted>
  <isquickfindquery>0</isquickfindquery>

  <returnedtypecode>10008</returnedtypecode>

          <link-entity name="wl_postalcode" from="wl_postalcodeid"

            <attribute name="wl_city" />
          </link-entity>
        </link-entity>

    </fetch>

GridXML仅限于显示主要实体和第一个链接实体的属性吗？

Answer 1

据我所知,这是不可能的,但请有人证明我错了.

GridXML的限制似乎是只能包含来自第一个链接实体的属性,而不是任何嵌套的链接实体.
