Alternative formula to replace the value based on previous cell value

[Nilkanth]

Hi,

I used below formula to replace the value based on theprevious value using Index column but it takes too much time to load and when I apply the next step it show the error. Is there any alternative formula I can use?

 Table.AddColumn(#"Added Index", "Custom", each if ConScorecard[Hours]{[Index]} = ConScorecard[Hours]{[Index]-1} then "0" else ConScorecard[Hours]{[Index]})

Thank you!

@Nilkanth,

You may use RANKX Function to add a calculated column.

Hi,

I have a table which has 10 columns. One of the column has duplicate value for the same month which I want to replace with "0". Please look at the highlighted cell value which I want to replace with "0" because those are duplicate value. I can't run remove duplicate function because it will eliminate entire row, which has some data I may not want to lose.

 

Thank you!
