大家好,

我已经使用Mobile Development Kit呆了一段时间,并尝试基于SAP Cloud Platform移动服务中的示例服务" com.sap.edm.sampleservice.v2"开发一个粗糙的示例应用程序。 到目前为止,一切正常,但是现在我遇到了以下问题。 我想通过以下操作创建一个实体类型为" SalesOrderItem"的实体:

{" ActionResult":{" _Name":" result"}," CreateLinks":[{" Property":" Header"," Target":{" EntitySet":" SalesOrderHeaders"," ReadLink":" /SalesOrdersOnline/Rules/Common/ChangeSet/ChangeSetSwitchReadLink.js"}},{" Property":" ProductDetails"," Target":{" EntitySet":" Products"," QueryOptions":" $ filter = ProductId eq'{ {#Control:ObjectCellListPickerProductId/#Value/#First/#Property:ReturnValue}}'"}}]," OnFailure":"/SalesOrdersOnline/Actions/CreateUpdateDelete/CreateEntityFailure.action"," OnSuccess":"//SalesOrdersOnline/Rules /Common/ChangeSet/CreateEntitySuccess.js","属性":{" CurrencyCode":"#ClientData/#Property:Product/#Property:CurrencyCode"," DeliveryDate":" #Control:DatePickerDeliveryDate/#Value"," GrossAmount ":"/SalesOrdersOnline/Rules/SalesOrder/SOItemCreateUpdate/GrossAmount.js"、"ItemNumber":"/img/SalesOrdersOnline/Rules/SalesOrder/SOItemCreateItemNumber.js"、"NetAmount":"/img/SalesOrdersOnline/Rules/SalesOrder/SOItemCreateUpdate/NetAmount。 js"," ProductId":" #Con trol:ObjectCellListPickerProductId/#Value/#First/#Property:ReturnValue"," Quantity":"#Control:SimplePropertyQuantity/#Value"," QuantityUnit":"#Control:SimplePropertyQuantityUnit/#Value"," SalesOrderId":"/img/SalesOrdersOnline/Rules/SalesOrder/GetSalesOrderId.js"," TaxAmount":"/img/SalesOrdersOnline/Rules/SalesOrder/SOItemCreateUpdate/TaxAmount.js"},"目标":{" EntitySet":" SalesOrderItems"," Service":"/img/SalesOrdersOnline/Services/SampleSrv.service"}," ValidationRule":"/SalesOrdersOnline/Rules/SalesOrder/SOItemCreateUpdate/Validation.js"," _Type":" Action.Type.ODataService.CreateEntity"}

如果我仅对" Header"导航属性包括CreateLink,则工作正常,但是当我对" ProductDetails"导航属性也使用CreateLink时,就会遇到以下错误:

"名称为ProductDetails的属性不参与任何OData关联。无法返回partnerPath。"

有人知道这可能是什么原因吗?
