您需要分两步完成此操作，首先使用API位置查询位置，然后在销售订单中传递值
1.

<query>
    <object>LOCATIONENTITY</object>
    <select>
        <field>LOCATIONID</field>
        <field>NAME</field>
        <field>RECORDNO</field>
    </select>
</query>

结果

<result>
                  <status>success</status>
                  <function>query</function>
                  <controlid>controlid</controlid>
                  <data listtype="LOCATIONENTITY" totalcount="1" offset="0" count="1" numremaining="0">
                        <LOCATIONENTITY>
                              <LOCATIONID>100</LOCATIONID>
                              <NAME>Test</NAME>
                              <RECORDNO>1</RECORDNO>
                        </LOCATIONENTITY>
                  </data>
            </result>
      </operation>
