I am trying to calculate the total quantity by Quality from a table called "Data", but filtering on the highest value in Period (in this case, 201906). The purpose is to calculate the variance for each quality (highest period/lowest period).
In other words, I would like to get for each product Quantity [Period 201906] / Quantity [Period 201902]
I have tried different formulas but I'm struggling with the filter context.
Can anyone help me?
Solved! Go to Solution.
Create a DAX formula that goes something like this:
Measure IsHighest = VAR __table = SUMMARIZE(ALLSELECTED('Table'),[Quality], [Period],"__Quantity",SUM([Quantity])) VAR __max = MAXX(__table,[__Quantity]) VAR __period = MAXX(FILTER(__table,[__Quantity] = __max),[Period]) RETURN IF(MAX([Period]) = __period,1,0)
Then just fiilter on this being 1
Thanks @Anonymous and @Greg for your solutions. My description of the issue is probably not accurate enough. What I am looking for is not retrieving the minimum quantity for each quantity. I want to retrieve the quantity for the Maximum value in "Period".
So for Quality "A", I want to retrieve the quantity where the value "Period" is the highest, so 10, not 13.
Then I would like to do the same for the minimum Period (so retrieve Quantity 5 for Quality A in @Anonymous 's example).
In the end, I would divide the Quantity for the highest Period by the Quantity for the lowest Period, for each Quality. That would give me an index, which is the scope of all the above.
I thought that DAX was the right language to solve this question but I didn't figure out how, despite may trials.
Thanks again for your help!
OK. So you need another table (created in PQ) that for each quality will store the quantities for the latest and oldest period.
I'll post a link to a file shortly.
