我有一个SmartField，我想连接到 ODATA 服务以valueHelp免费获得。
指向 ODATA 服务的模型如下所示：
"EAMMALFUNCTION": {
"uri": "/sap/opu/odata/sap/EAM_MALFUNCTION_MANAGE/",
"type": "sap.ui.model.odata.v2.ODataModel",
"settings": {
"defaultOperationMode": "Server",
"defaultBindingMode": "OneWay",
"defaultCountMode": "Request"
},
"dataSource": "EAM_MALFUNCTION_MANAGE",
"preload": true
}
实体集的 uri 是/sap/opu/odata/sap/EAM_MALFUNCTION_MANAGE/I_PMContactCardEmployee，元定义是：
<EntitySet Name="I_PMContactCardEmployee" EntityType="EAM_MALFUNCTION_MANAGE.I_PMContactCardEmployeeType" sap:creatable="false" sap:updatable="false" sap:deletable="false" sap:searchable="true" sap:content-version="1"/>
<EntityType Name="I_PMContactCardEmployeeType" sap:label="Mitarbeiter" sap:content-version="1">

</EntityType>
提供以下数据：
{

"id": "https://example:4000/sap/opu/odata/sap/EAM_MALFUNCTION_MANAGE/I_PMContactCardEmployee('00000019')",

我想要存档的是，连接SmartFieldODATA 服务并valueHelp免费获得，无需任何特定编码以获得价值帮助。
当我在值帮助上选择一个值时，它应该将PersonnelNumber插入到SmartField.
这I_PMContactCardEmployee是一个 CDS 消费视图，它提供了一个搜索帮助的界面：
@AbapCatalog.sqlViewName: 'IPMCONTCARDEMP'
@AbapCatalog.compiler.compareFilter: true
@AccessControl.authorizationCheck: #CHECK
@VDM.viewType: #COMPOSITE
@EndUserText.label: 'Employee'
@ObjectModel.representativeKey : 'PersonnelNumber'
@Search.searchable: true
@ClientHandling.algorithm: #SESSION_VARIABLE
@ObjectModel.usageType.dataClass: #MASTER
@ObjectModel.usageType.serviceQuality: #D
@ObjectModel.usageType.sizeCategory: #L
@AccessControl.personalData.blocking: #REQUIRED
define view I_PMContactCardEmployee
我已经尝试将 SmartField 与I_PMContactCardEmployee服务连接，如下所示：
<smartField:SmartLabel labelFor="pmAssignTo" />
<smartfield:SmartField id="pmAssignTo" binding="{EAMMALFUNCTION>/I_PMContactCardEmployee}" value="{PersonnelNumber}">
<layoutData>
<layout:GridData span="L7 M7 S12"/>
</layoutData>
</smartfield:SmartField>
我收到了错误消息：
Uncaught (in promise) Error: Cannot add direct child without default aggregation defined for control sap.ui.comp.smartfield.SmartField
