A slicer to use in multiple columns

[Anonymous]

Hello to all

I have the following table:

C1     C2     C3    C4

a

b       a   

a       b       c

d

b      c        d      a

How can I slice it to find the rows that have a a? (in this case 1,2,3,5)

I saw some post sugesting a union first to use on the slicer but I do no know how many Columns I have because the table is build using a power query function.

Thanks

Create a paramter table Params that has one column Value:

Value
a
b
c
d

Make sure this table does not have a relationship with the other table. Place Params[Value] in a slicer. Create a measure as follows (TT is your original table):

Measure = IF(HASONEVALUE(Params[Value]), 
	         IF(MAX(TT[C1]) = MAX(Params[Value]) ||
		    MAX(TT[C2]) = MAX(Params[Value]) ||
		    MAX(TT[C3]) = MAX(Params[Value]) ||
		    MAX(TT[C4]) = MAX(Params[Value]),
		    1,
		    0), 
	  1)

In your visual, place this measure among the filters for your table and enter Show Items When Value is 1. Now if you select "a" in your slicer, your table will only show rows where the measure evalutes to 1 and you should have achieved your objective.

@erik_tarnviktried your solution and almost solved my problem. In fact I do not know the number of columns my table has because it is build using a power query function. How can we change the measure to make reflect the case we have more than 4 columns?

Understand. In that case the approach mentioned by @@Rodrigo_Carva may be worth trying. Use Power Query to merge all pertinent columns in your table into one single column and use that column to determine the precense of the selected value. I.e your table becomes

C1     C2     C3    C4      Combined

a                                   a

b       a                          ba

a       b       c                 abc

d                                   d

b      c        d      a         bcda

Then adjust the measure I suggested to:

Measure = IF(HASONEVALUE(Params[Value]), 	         
               IF(FIND(MAX(Params[Value]), MAX(TT[Combined]),1,0) <> 0,
		    1,
		    0), 
	  1)

If you do not know the number of columns I just can think about creating on Power query a column that says if some of the built columns has an "a". Other option would be to have a column on Power query that concatenates the other columns and treat that on DAX finding an "a" on it.
