Power BI Power Query filter main table with two tables based on columns from both

Question

我有一个 table 发票，必须针对某些供应商和某些帐号进行过滤。必须过滤的供应商和帐号都在两个小 excel 文件中。我如何将它们与主要 table 结合起来，以便针对帐号或供应商编号过滤主要 table？

Answer 1

有几种方法可以做到这一点。这是一个解决方案，它通过分别筛选供应商和帐号来创建两个发票编号列表，然后将它们组合成一个用于筛选主要 table.

的列表

这里是使用的示例 table（全部包含在下面的 M 代码中）：

主表

供应商过滤器

帐户过滤器

这是您可以粘贴到空白查询中的 M 代码：

let
    // Import sample tables and edit data types if needed
    SourceMainTable = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("VY+7DcAgDAV3oabwB4dQZok0EfuvkWcLJNMg3p3Qie8rRFxqYSOcr18fgFldCNYILgdXLOEQeoiG1SlECyFLGJZSSmxxYbWU2Lx7wlJCl7j9QU+JLYb/glNiiUCWEuDzBw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Invoice = _t, Value = _t, Vendor = _t, Account = _t]),
    MainTable = Table.TransformColumnTypes(SourceMainTable,{{"Invoice", type text}, {"Value", Int64.Type}, {"Vendor", type text}, {"Account", type text}}),
    VendorFilter = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCjNWitUBUiZKsbEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Vendor = _t]),
    AccountFilter = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcjQwVoqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Account = _t]),
    
    // Extract lists of invoice numbers filtered for vendors and for account numbers separately
    ListInvoicesFilteredVendors = Table.SelectRows(MainTable, each List.Contains(VendorFilter[Vendor], [Vendor]))[Invoice],
    ListInvoicesFilteredAccounts = Table.SelectRows(MainTable, each List.Contains(AccountFilter[Account], [Account]))[Invoice],
    
    // Combine both lists of invoice numbers into one list and use it to filter main table
    ListInvoicesCombined = List.Distinct(List.Combine({ListInvoicesFilteredVendors, ListInvoicesFilteredAccounts})),
    FilteredTable = Table.SelectRows(MainTable, each List.Contains(ListInvoicesCombined, [Invoice]))
in
    FilteredTable

这是结果，您可以看到发票 001、002、005 和 006 不包括在内，因为它们不包含 V3、V4 或 A03：
