I have a dimension with a hierarchy that changes every year. Maybe I can solve this by altering the the model but I would really like to know if there is an expression I can write in a listbox to filter my values.
Dimension:
Year
Level1
Level2
2015
Fruits
Apple
2015
Fruits
Banana
2015
Fruits
Orange
2014
Apple
SubApple
2014
Banana
SubBanana
2014
Orange
SubOrange
So If I put Level1 as a dimension I want to filter it to only show the rows relevant to the selected year.
I do not want to tick 'Hide Excluded' because I want to show the excluded values (Just not for the other years)
If I make an expression as the field in the listbox, i.e
if(Year=GetFieldSelections(Year),Level1)
it works. But!, when I then select/deselect my fruits in the listbox I also select/deselect Year!? and if I go to my year listbox and tick 'always one selected value' then I cant deselect my fruits in Level1 listbox.
Is there another expression I can use? can I use set analysis in anyway?
