DAX Switch & nested IF

i can't belive there is no solution for this,

 i need a simple dax measure 

IF( ISINSCOPE( HIER[LEVEL_7_DESC] ), 17, IF( ISINSCOPE( HIER[LEVEL_6_DESC] ), 16, IF( ISINSCOPE( HIER[LEVEL_5_DESC] ), 15 ) ) )

this doesn't work because if i change the order of column in the visual then the higher or the first condtition will always be the only one is true returning this value only?!!

I left a comment on your original post, but here it is agian: 

Realistically, a field parameter would be a better implementation of this situation than a DAX Switch statement. For the field parameter, you would select/add every measure you would like a user to select from (like what you have in the switch statement) and use this as a slicer on the page. Also with a field parameter, you can select multiple values and each value will appear and not get ignored like a Switch statement would. 

To add onto this, if you need the ability for end-users to select multiple data elements a field parameter would be a better solution than nested IF's or Switch statements. Here's the documentation for field parameters: Use report readers to change visuals - Power BI | Microsoft Learn

Hi @Maximous89 , Thank you for reaching out to the Microsoft Community Forum.

As you haven't shared any data and it is very hard to provide a solution without it, I took some sample data based on your scenario and created a .pbix file with a working solution for you reference. Please check the attached .pbix file and share your thoughts.

Thank you.

hi @Maximous89 ,

Please share some sample data and expected output to understand the ask. sometimes only looking at the DAX doesn't help but the entire scenario does.

Hi @Maximous89 

You could use a measure that checks which level has a non-blank value, assuming each level is only populated when it's relevant:

LevelNumber = 
SWITCH(
    TRUE(),
    NOT(ISBLANK(SELECTEDVALUE(HIER[LEVEL_7_DESC]))), 17,
    NOT(ISBLANK(SELECTEDVALUE(HIER[LEVEL_6_DESC]))), 16,
    NOT(ISBLANK(SELECTEDVALUE(HIER[LEVEL_5_DESC]))), 15,
    BLANK()
)

I hope this helps

Weird when you say 'i can't belive there is no support on this'.. I clicked open your original post and saw Community support followed up twice on your question there.
