Thanks for the response, the original data has several more columns. Unpivoting will mess up other calculations which I'm trying to avoid. Please advise if theres alternate method.

 

Original data also has 100s of different part numbers.

 

Thanks.

Hi vincentakatoh ,

 

We can use the following steps to meet your requirement:

 

1. create a custom column in fact table:

 

"," & Text.Combine(List.Transform(Record.ToList(Record.SelectFields(_,List.Select(Table.ColumnNames(NameOfYourLastStep), each Text.Contains(_, "PartNumber")))), Text.From), ",") & ","

 

 

2. Create another query table:

 

let
    Source = Table.SelectColumns(FactTable,List.Select(Table.ColumnNames(FactTable), each Text.Contains(_, "PartNumber"))),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(Source, {}, "Attribute", "Value"),
    #"Removed Other Columns" = Table.SelectColumns(#"Unpivoted Columns",{"Value"}),
    #"Removed Duplicates" = Table.Distinct(#"Removed Other Columns")
in
    #"Removed Duplicates"

 

 

3. create a measure to calculate the result:

 

Count = SUMX(DISTINCT('Query1'[Value]),var v=[Value] return SUMX('FactTable',round(DIVIDE(LEN([Custom])-LEN(SUBSTITUTE([Custom],","&v&",","")),LEN(","&v&","),0),0)))

 

 

we use the Text.Contains(_, "PartNumber") to determine the partnumber column, if mean the condition of column name is it contain "Part Number", you can use Text.StartsWith(_, "PartNumber_Part replace_") , it will be more Strict.


By the way, PBIX file as attached.
