我正在将Salesforce中的数据集成到另一个API中。源有1个具有相关子对象的对象。但是，目标API需要采取如下形式。子对象中的每个相关Salesforce记录都需要子表单中的节点。下面的POST示例是有效载荷的最终所需形式。
我想我需要使用DataWeave，使用For Each来跟踪Salesforce中的每个子记录。但我不太清楚从哪里开始。
以下是来自Salesforce帖子主题的传入JSON：
{
"LastModifiedDate": "2016-09-22T14:19:08.000+0000",
"Engagement__c": "1234",
"Product_CoC__c": null,
"Name": "Prod-22880",
"Year_1_Approved_Production_Hectares__c": 100.0,
"Year_1_Approved_Production_Volume__c": 1000.0,
"Product_Variety__c": null,
"CreatedById": "1234",
"Year_2_Estimated_Production_Volume__c": 1001.0,
"Product__c": "1234",
"Engagement_Decision_Date__c": null,
"Year_1_Harvest_Period__c": "2016",
"CPH_Number__c": null,
"Product_Type__c": null,
"Certificate_Product__c": "1234",
"IsDeleted": false,
"Crop_Yield__c": 10.0,
"Year_2_Estimated_Production_Hectares__c": 100.0,
"Valid_Period_End_Date__c": null,
"Intercrop__c": false,
"SystemModstamp": "2016-09-22T14:19:08.000+0000",
"Year_2_Harvest_Period__c": null,
"Crop_Production_Unit__c": "kg",
"Certificate__c": "1234",
"Year__c": 1.0,
"Harvest_Frequency__c": "Single",
"CreatedDate": "2016-07-28T15:44:18.000+0000",
"Valid_Period_Start_Date__c": null,
"Id": "1234",
"LastModifiedById": "1234",
"RA_Id__c": null
}
这是我对子对象的转换消息：
