I need direction or exact formula help in power query. I am trying to calculate the sum of columns if condition is true, and bringing the result in new column. The code is Below;
({If [Num] = 1 Then Sum([Column1](Value),[Column3](Value)}),
If Column(Num) equlas 1 then add values in column1 and 3 If Column(Num) = 2 then add values in column2 and column3 Maybe I need to use GroupBy...
In brief what I want to do is use sumif in excel
Based on your original question and the comments, it appears you only want to add the numbers in the same row under certain conditions of column 3 (or Num in your revised question).
Try:
=if [Column3] = 1 then [Column9] + [Column12] else null
or, in native M-Code:
#"Added Custom" = Table.AddColumn(#"Changed Type", "New Column Name", each if [Column3] = 1 then [Column9] + [Column12] else null)
