在水壺中使用發票行拼合發票擡頭

Question

如果您的發票擡頭包含多個值（發票編號，日期，位置）和具有多個值（產品，價格，稅額）的未知數量的發票行，是否有辦法將這些數據平鋪到一行，這在發票行數量因發票而異的情況下得以延長？

輸入例 -

{"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", 
     "UniqueID": "34", 
     "taxCode": "SALES TAX", 
     "taxrate": "7.25", 
     "maxtax": "0" 
    }] 
}]} 

我需要在同一行中的所有項目（允許有更比一個行項目和/或在給定的發票超過一個稅法的項目。記錄

你有一個samples目錄中類似問題的例子，它位於你的spoon.bat附近。看一下samples/transformation/XML Add並且在第一個choc中生存：他們做更復雜的事情，只是爲了展示所有可能的事情。

在你的情況下，分割爲Switch/Case，輸入流在標題，項目，並設法保持每個發票號碼（稍後更多）。將三個流轉換爲JSON（使用JSON輸出，或者更簡單，使用Javascript）。然後你通過發票號碼Group by項目。通過InvoiceNumber加入三個流程，爲此我建議在頁眉流中輸入lookup stream，然後在頁腳流中輸入其他lookup stream。使用另一個javascript並將數據視爲字符串，可以使用格式爲{header，[item]，footer}的格式構建JSON行，您可以將Group by連接爲只有一行。

一些工作，但標準，除了棘手的部分獲取物品和頁腳上的發票號碼，因爲他們已從流中消失。爲此，您可以使用javascript保留值的事實，除非重新定義。添加一個新的啓動腳本[右鍵單擊標籤頂部的Script1，添加一個副本，右鍵單擊剛創建的Script1_0，並將其定義爲啓動腳本]。

在此啓動腳本：

var PrevInvoiceNumber = -1; 

在主腳本：

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

那麼你應該看到的數據，每行的PrevInvoiceNumber等於發票的預期InvoiceNumber 。
