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

Hi,

I have three columns. I would like to keep only duplicate value and replace the others with zero. Is there a way to accomplish that?

*Note: Count is calculated column.

Author	Count	%	Final outcome
Apple	8	30%	30%
Apple	8	30%	0%
Apple	37	40%	40%
Apple	37	40%	0%
Apple	37	40%	0%
Boy	2	10%	10%
Boy	2	10%	0%
Boy	2	10%	0%
Boy	2	10%	0%

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.

Hi,

I am trying to use these formulas for power query, however, it keeps returning syntax errors. I think the issue I have is settign up the calculated column reference. I cannot use these formulas within a custom column field.

Can you please explain how you are building this column?
