Rank with filter
I have table :
Sales
ProductCat ProductGroup Sales
1 1 100
2 1 105
3 2 34
4 2 23
5 5 1000
I need to filter out Product Cat 5 and then add a rank column, partitioned by ProductGroup i.e. :
ProductCat ProductGroup Sales Rank
1 1 100 2
2 1 105 1
3 2 34 1
4 2 23 2
I can do the rank with :
ADDCOLUMNS('Sales', "Rank", RANKX(CALCULATETABLE('Sales', ALLEXCEPT('Sales', 'Sales[ProductGroup]), 'Sales'[Sales])
One thing I'm struggling with filtering out ProductCat 5 before running the RANKX. I tried adding it into CALCULATETABLE as an additional filter but this has no effect due to the ALLEXCEPT. I've tried a nested CALCULATETABLE with the filter but this has no effect either.
Any ideas how I can apply a filter prior to CALCULATETABLE?
Easy answer is to try this:
SalesRank = ADDCOLUMNS(FILTER(Sales,Sales[ProductGroup]<>5),"Rank", RANKX(ALLSELECTED(Sales), [TotalSales]))So basically filter the Sales table before you add columns to it.I wonder though, is there a reason you're using DAX ADDCOLUMNS to create a new table? How do you need to use this in the report and should the rank update if you filter out another product category.One thing you can do is use a MEASURE instead. That will enable you to create a table visualization that can have the measure added to it. Then you can filter that visual to exclude category 5 and the rankings will update.

Just to clarify. Are you trying to make a measure? calculated column? or calculated table? Depending on what your goal, I would suggest a simpler DAX expression to achieve your goal.
FYI that you can just add a term to your Calculatetable( ) expression to filter out ProductCat <> 5 after the Allexcept() clause. Note there seems to be a missing parentheses after that anyway.

If this works for you, please mark it as the solution. Kudos are appreciated too. Please let me know if not.

I'm sticking with table at the moment as there's more processing to do. We can't add filters in CALCULATE as filter context is being amended by allselected().
I will try applying the filter in an outer calculate.This article explains it all
