在 Power Query(M 代码)中,假设您的数据具有代表性,您可以在过滤/分组等之前计算 QoQ 值。
- 在显示时添加索引列
- 然后添加一个模数列(值 = 4,因为您有四个季度)
- 然后为您的两个计算添加自定义列:
这是假设数据源是 Excel 表的 M 代码。根据需要修改 Source 行
let
Source = Excel.CurrentWorkbook(){[Name="Table7"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Qtr", type text}, {"Filter", type text}, {"Imp", Int64.Type}, {"Eng", Int64.Type}}),
//Compute % Eng column
#"Added Custom" = Table.AddColumn(#"Changed Type", "% Eng", each [Eng]/[Imp], Percentage.Type),
//Add Index and Modulo columns
#"Added Index" = Table.AddIndexColumn(#"Added Custom", "Index", 0, 1, Int64.Type),
#"Inserted Modulo" = Table.AddColumn(#"Added Index", "Modulo", each Number.Mod([Index], 4), type number),
//Compute QOQs -- (current row - previous row)/previous row (unless first row in the group in which case => null
#"Added Custom1" = Table.AddColumn(#"Inserted Modulo", "QoQ Imp", each if [Modulo]=0 then null
else ([Imp] - #"Inserted Modulo"[Imp]{[Index]-1}) / #"Inserted Modulo"[Imp]{[Index]-1}),
#"Added Custom2" = Table.AddColumn(#"Added Custom1", "QoQ %Eng", each if [Modulo]=0 then null
else ([#"% Eng"] - #"Inserted Modulo"[#"% Eng"]{[Index]-1}) / #"Inserted Modulo"[#"% Eng"]{[Index]-1}),
//remove now superfluous Index and Modulo columns and re-order the others
#"Removed Columns" = Table.RemoveColumns(#"Added Custom2",{"Index", "Modulo"}),
#"Reordered Columns" = Table.ReorderColumns(#"Removed Columns",{"Qtr", "Filter", "Imp", "QoQ Imp", "Eng", "% Eng", "QoQ %Eng"})
in
#"Reordered Columns"
