avoid double count, power query equivalent for excel solution?

Hello,

 

I'm trying to find an equivalent or alternative solution for below excel example. Column B containts the (original) quantities, column C the calculated ones, where the value is set to 0 (zero) where the ID in column A already occurs earlier in previous rows. (the outcome in cell C8 is 0), same as the cell above. 

the totals in cells B9 and C9 are only for illustration purposes and are not needed as such.

I'd posted this question earlier attempting to explain what I need in power bi, but without this excel reference. I hope this both clarifies what I'm after and triggers a solution. 

 

thanks,

Hi @Anonymous 

In Power BI, before any transformation,

firstly you could go to Home->Edit queries,

Add column->add an index column from 1,

Then close&&apply and return to Report view, 

Create measures

Measure = CALCULATE(MIN(Table1[Index]),ALLEXCEPT(Table1,Table1[id]))

Measure 2 = IF(MAX(Table1[Index])=[Measure],SUM(Table1[q]),BLANK())
