Hi, so here is my use case: I need create a ranking of a column based on sales, but this ranking must change based on the column selected witht he dynamic parameter. So I may have selected "Name" from Table A in the dynamic parameter, and it will create a ranking of all my names. Then I may select "Region" from Table B by changing the parameter selection and now my ranking will change to reflect the regional ranking against sales instead. I have done this with static columns for a use case but now I need to make it work dynamically.
Here is the dax i have been using till now:
RANKX( FILTER( ALLSELECTED ('Column'), NOT ISBLANK( [Sales] )), [Sales], , DESC, Dense)
Here is the dax I need it to work as:
RANKX( FILTER( ALLSELECTED ('Dimensions'[Column Selection] ), NOT ISBLANK( [Sales] )), [Sales], , DESC, Dense)
But this doesnt work and gives me the following error that the column is part of a composite key.
