在水壶中使用发票行拼合发票抬头

Question

如果您的发票抬头包含多个值（发票编号，日期，位置）和具有多个值（产品，价格，税额）的未知数量的发票行，是否有办法将这些数据平铺到一行，这在发票行数量因发票而异的情况下得以延长？

输入例 -

{"InvoiceRecords": [{ 
    "InvoiceDate": "8/9/2017 12:00:00 AM", 
    "InvoiceLocation": "002", 
    "InvoiceNumber": "2004085", 
    "InvoiceRecordHeaderDetails": [{ 
     "InvNum": "2004085", 
     "Location": "002", 
     "InvDate": "8/9/2017 12:00:00 AM" 
    }], 
    "InvoiceRecordLineItemDetails": [{ 
     "UniqueID": "3939934", 
     "InvNum": "2004085", 
     "LINEITEM": "1", 
     "CUSTID": "PREAA", 
     "DEPTID": "320306", 
     "PRODID": "088856", 
     "ProdDesc": "STATE UST", 
     "Unitprice": "0.003", 
     "QuantShare": "237.5", 
     "TaxRate": "7.25", 
     "taxamount": "0.05" 
    }], 
    "InvoiceTaxCodeDetails": [{ 
     "InvNum": "2004085", 
     "LineItem": "1",

     "taxCode": "SALES TAX", 
     "taxrate": "7.25", 
     "maxtax": "0" 
    }] 
}]} 

我需要在同一行中的所有项目（允许有更比一个行项目和/或在给定的发票超过一个税法的项目。记录

你有一个samples目录中类似问题的例子，它位于你的spoon.bat附近。看一下samples/transformation/XML Add并且在第一个choc中生存：他们做更复杂的事情，只是为了展示所有可能的事情。

在你的情况下，分割为Switch/Case，输入流在标题，项目，并设法保持每个发票号码（稍后更多）。将三个流转换为JSON（使用JSON输出，或者更简单，使用Javascript）。然后你通过发票号码Group by项目。通过InvoiceNumber加入三个流程，为此我建议在页眉流中输入lookup stream，然后在页脚流中输入其他lookup stream。使用另一个javascript并将数据视为字符串，可以使用格式为{header，[item]，footer}的格式构建JSON行，您可以将Group by连接为只有一行。

一些工作，但标准，除了棘手的部分获取物品和页脚上的发票号码，因为他们已从流中消失。为此，您可以使用javascript保留值的事实，除非重新定义。添加一个新的启动脚本[右键单击标签顶部的Script1，添加一个副本，右键单击刚创建的Script1_0，并将其定义为启动脚本]。

在此启动脚本：

var PrevInvoiceNumber = -1; 

在主脚本：

if(InvoiceNumber && PrevInvoiceNumber!=InvoiceNumber) 
    PrevInvoiceNumber = InvoiceNumber 

那么你应该看到的数据，每行的PrevInvoiceNumber等于发票的预期InvoiceNumber 。
