How do I replace duplicates values with zero in a column based on other two columns.

Hi,Khushboo9966

1.Add the index column to the powerquery:

2.Create calculated column references:

Column = 
VAR FIRST=CALCULATE(MIN('Table'[Index]),ALLEXCEPT('Table','Table'[Author],'Table'[Count]))
RETURN IF('Table'[Index]=FIRST,'Table'[%],BLANK())

Column 2 = 
VAR CI='Table'[Author]
VAR ci2='Table'[Count]
VAR RANKC=RANKX(FILTER('Table','Table'[Author]=CI&&'Table'[Count]=ci2),'Table'[Index],,ASC,Dense)
RETURN IF(RANKC=1,'Table'[%],BLANK())

I've given you two options that you can choose according to your needs.

3.Here's my final result, which I hope meets your requirements.
