如何用列 (M) 中的最新日期替换值

Question

我试图将特定值 (Contagem) 替换为列数据中找到的最早日期（减去 01 天），但我不知道如何替换。这个想法是设置这个最早的日期 - 1 天作为库存盘点的初始日期，然后会有其他日子跟随移动。

let
    Fonte = Excel.Workbook(Web.Contents("https://docs.google.com/spreadsheets/d/e/hdsdshjdsh/pub?output=xlsx"), null, true),
    Previsão_Sheet = Fonte{[Item="Previsão",Kind="Sheet"]}[Data],
    #"Cabeçalhos Promovidos" = Table.PromoteHeaders(Previsão_Sheet, [PromoteAllScalars=true]),
    #"Tipo Alterado" = Table.TransformColumnTypes(#"Cabeçalhos Promovidos",{{"Previsão de Produção", type text}, {"Column2", type any}, {"Column3", type any}, {"Column4", type text}, {"Column5", type text}, {"Column6", type any}, {"Column7", type any}, {"Column8", type any}, {"Column9", type any}, {"Column10", type any}, {"Column11", type any}, {"Column12", type any}, {"Column13", type any}, {"Column14", type any}, {"Column15", type any}, {"Column16", type any}, {"Column17", type any}, {"Column18", type any}, {"Column19", type any}, {"Column20", type any}}),
    #"Linhas Principais Removidas" = Table.Skip(#"Tipo Alterado",3),
    #"Cabeçalhos Promovidos1" = Table.PromoteHeaders(#"Linhas Principais Removidas", [PromoteAllScalars=true]),
    #"Colunas Removidas" = Table.RemoveColumns(#"Cabeçalhos Promovidos1",{"Local"}),
    #"Outras Colunas Não Dinâmicas" = Table.UnpivotOtherColumns(#"Colunas Removidas", {"Und", "Descrição", "Cód.", "Categoria"}, "Atributo", "Valor"),
    #"Linhas Filtradas" = Table.SelectRows(#"Outras Colunas Não Dinâmicas", each Text.Contains([Atributo], "/") or [Atributo] = "Contagem"),
    #"Colunas Renomeadas" = Table.RenameColumns(#"Linhas Filtradas",{{"Atributo", "Data"}})
    #"Valor Substituído" = Table.ReplaceValue(#"Colunas Renomeadas","Contagem","31/01/2021",Replacer.ReplaceText,{"Data"})
    //#"Valor Substituído" = Table.ReplaceValue(#"Colunas Renomeadas","Contagem", List.Max(Table.RemoveRowsWithErrors(#"Tipo Alterado", {"Atributo"})[Data]),Replacer.ReplaceText,{"Data"})
in
    #"Valor Substituído"

最后两行是应该实施解决方案的地方，但是...

如有任何帮助，我将不胜感激。

干杯，安东尼奥

看看这样的东西是否适合你

将数据列转换为文本
删除所有其他列
将数据列更改为日期
删除所有有错误的行
使用 List.Min() 获取最小日期，减去一个，使用 Text.From()
编辑 - 用新值替换原始数据列的文本

样本

#"Changed Type" = Table.TransformColumnTypes(#"Colunas Renomeadas",{{"Data", type text}}),
newdate= Date.AddDays(List.Min(Table.RemoveRowsWithErrors(Table.TransformColumnTypes(Table.SelectColumns(#"Changed Type",{"Data"}),{{"Data", type datetime}}), {"Data"})[Data]),-1),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type","Contagem",Text.From(newdate),Replacer.ReplaceText,{"Data"})
in #"Replaced Value"
