DAX Help

[Anonymous]

I have two columns and need create a slicer/DAX formula for below scenerio.

Example :

I have to create flag (yes or No) and create slicer for this flag.

For No = Everything should be shown, i.e. no filter applied. - It should take all the values from List X
For Yes = The values in the List Y need to be avoided from List X. ( only pick B,D,E values)

What is the best approach or DAX formula that fulfil this requirment.

List X	List Y
A	A
B	C
C	F
D
E
F

Hi @Anonymous,

I'm assuming you have two separate tables. Create a disconnected table with Yes and No values then add the following measure to filter your data:

Filtering values = IF(SELECTEDVALUE('Filter'[Filter]) = "No"; MAXX(FILTER(ListX;ListX[List] in VALUES(ListY[ListY]));ListX[List]);BLANK())

Now use this measure as a filter on the visualization you need and select all values that equal blank.
