Java KSOAP2请求正文格式问题

我在SAP ECC 6.0中激活了一个服务，我能够从生成以下SOAP请求的SOAP UI 5中成功测试该服务

SOAPUI 5.0生成的请求成功运行

然而，当我使用下面的代码从ksoap2api调用此服务时，我无法得到正确的响应，相反，我得到了元素丢失错误

基于android代码生成错误请求

下面是代码生成的soap请求，其中缺少一个元素，但我不确定如何使用KSOAP2 API将其添加到请求中

由上述代码创建的请求

必需的

我想在soap请求中添加第一个请求的标记，但无法这样做

其他信息：

在PurchaseOrderItemSelectionByAccountAssignment标记下面可能有多个参数，但我只使用PurchaseOrderItemAccountAssignmentCostCentreID参数

有人知道我哪里出错了，以及如何更改它以创建正确的soap请求吗

关于这一点，

我的问题已通过以下链接中讨论的KVM串行化接口实现得到解决

这本质上是一个实现复杂类型的案例

经验教训：如果您在创建/解析soap请求或响应时遇到问题，请将您的WSDL及其内容映射到KSOAP API，您将在进行一些研究后找到答案

您是在xml Format或json上发布数据吗？我是通过xml发布数据的，xml是由我上面使用KSOAP2粘贴的代码生成的。通过在stackoverflow上使用此链接解决了此问题。您可以分享一些关于创建SOAP请求主体的更多信息吗。以及将WSDL与KSOAP API映射
