锐浪报表，子报表没数据的原因

主要有两个原因
报表提供的json主数据如下。

{ 
    "Master": [
        {
            "Id": "3183a9cb-a546-43d2-aa6a-a0b3bc00d7fa",
            "MKBarcode": "011712111052",
            "SampleNo": "171214003",
            "HospitalBarcode": "",
            "HospitalName": "011712111052",
            "HospitalCode": "011712",
            "PatientName": "蒋之存"
        }
    ],
    "Details": [
        {
            //子表也要有这个字段。 字段名要一致，数值也要根据主表的一致
            "ReportDetailId": "b2b4fda5-b616-4a01-8bef-0d8aea7e992a",
            "ReportId": "3183a9cb-a546-43d2-aa6a-a0b3bc00d7fa",
            "TestItemCode": "171214003",
            "TestItemName": "嗜麦芽寡养单胞菌",
            "ReferenceValue": "其它",
            "TestValue": "",
            "TestUnit": "",
            "Hl": "",
            "InstrumentCode": "",
            "TestMethod": "",
            "TestTime": "1900-01-01 00:00:00",
            "SortCode": "1 ",
            "ODValue": "",
            "IsCMA": "",
            "ResultTypeName": "培养结果阳性",
            "TestAimsCode": "",
            "TestAims": ""
        }
    ], 
    "ThreeDetails": [
        {
            "Id": "05b563c8-f03c-4b87-95ec-709f57e97c50",
            "ReportId": "3183a9cb-a546-43d2-aa6a-a0b3bc00d7fa",
            //这个字段必须一致，字段名要一致，数值也要根据主表的一致
            "ReportDetailId": "b2b4fda5-b616-4a01-8bef-0d8aea7e992a",
            "SortCode": "1 ",
            "DrugCode": "",
            "DrugName": "左氟沙星",
            "TestValue": ">8",
            "Sensitivity": "耐药",
            "ReferenceValue": ""
        },
        {
            "Id": "2a07c683-c934-4056-a458-28e67fa73b16",

            "ReportId": "3183a9cb-a546-43d2-aa6a-a0b3bc00d7fa",
            //这个字段必须一致，字段名要一致，数值也要一致
            "ReportDetailId": "b2b4fda5-b616-4a01-8bef-0d8aea7e992a",
            "SortCode": "1 ",
            "DrugCode": "",
            "DrugName": "氨曲南",
            "TestValue": ">16",
            "Sensitivity": "耐药",
            "ReferenceValue": ""
        } 
    ]
}

Details 和 ThreeDetails之间的【主从关系字段】是 “ReportDetailId“，两个都必须有这个字段。且字段名字也要一样，都必须包含字段名为 ReportDetailId 。且值一样
字段名 Details 和 ThreeDetails 只能用一次。不要填两个地方。我就犯了个错误，把ThreeDetails填在了【子报表】对象的【报表主对象】的属性 “xml表名“ 中，同时在子报表的 “XML表名” 也填了ThreeDetails 这样就导致子报表的明细网格找不到数据了。因为已经先匹配给子报表的主对象了。
