任務：爲零件號創建一個報表，該零件號在日期桶中顯示幾種類型（現貨，訂單等），每種類型總計爲具體範圍。使用數組設置篩選查詢並在Access VBA中返回一系列計算
For example:
Item 1 => (could be over 2000)
2/5/2017 2/19/2017 2/28/2017 (30 weeks)
On Hand 20 42 33
On Order 0 5 4
每個項目都顯示在它自己的頁面上，包含關於該項目的相關元數據。每個日期桶基於用戶輸入的開始日期，並根據數據集運行計算以確定哪些桶以及總計的內容。
我有這個報告完全適用於一個項目。用戶類型一個項目，選擇一個日期，該報告使用以下方法創建：
Inventory Meta general information and description of the item
Inventory Detail gets all the detailed information
Inventory Totals gets totals for each Types
GetInventory() VBA sets up the buckets and populates the totals
使用查詢來獲取日期桶或許會更容易將數據放到報告。使用210個計算列（7種類型，30周）創建查詢不是一種合理的方法。
當然，一次選擇一個項目不是想要的。
我有一個選擇框，可以獲取所選部件編號併爲庫存元（主要報表）動態創建查詢。我有類似的代碼工作，與庫存彙總（子報告）一起運行，以便爲此動態創建查詢。
但是，與Inventory Totals查詢一樣，每個日期都是唯一值，並且是自己的行。我需要做的是運行代碼爲所選的每個項目構建桶。
我被卡住了。
我已經創建了一個項目編號數組（無論選擇了什麼）。我可以看到陣列中有什麼。
我似乎無法弄清楚的是如何將每個代碼提供給運行日期比較和計算的代碼，以便我可以獲得每個部件號的完整數據集。
有了一個號碼很容易......「這一個」
vItem = [Forms]![fOptions]![ItemNumber]
Set db = CurrentDb
strSelect = "Select * FROM qInventoryTotals WHERE qInventoryTotals.ItemNumber = [this_one]"
Set qdf = db.CreateQueryDef(vbNullString, strSelect)
qdf.Parameters("this_one").Value = vItem
Set inv = qdf.OpenRecordset
我來是要使報告中顯示的同一組數據的所有部分的數字最接近的一次。我懷疑有一些小而關鍵的東西，比如某個特定循環開始的位置或者我錯過的變量或其他東西。
以下結果是一個消息框，重複每個零件號的相同總數。
