Need a slicer which only shows the unique options in a column with a string separated by commas

[s_shafiq]

Hello,

I have some data which looks like this:

I need to add a slicer in the report view that only shows SINGULAR options, for example:

Bedfordshire Borough Council

Cambridgeshire County Council

Suffolk County Council

Peterborough City Council

etc.

etc.

I CANNOT split the column into additional rows because that will ruin all my visuals. The number of rows MUST remain the same, as each row pertains to a unique road.

Any help would be greatly appreciated!!

Hi

Intersting task. I created I sample file but cannot find a way to upload it (wasn't this possible a while ago?). I hope my description and screenshots help.

Steps

1. You need a unique identifier in your table. If you dont have one create it by adding an index column in Power Query.
   
   
   
2. In Power Query duplicate the LHAs column named e.g. "LHAs -Copy"
3. Split the "LHAs -Copy"column into new columns (by comma) --> you will get several new columns depending on how many values are packed most in one LHA column. In my test file this creates 4 columns, let's call them LHA1-4.
   
4. Create a new table by referencing the base table, let's call it "Filter Table"
5. In the "Filter Table" only keep the unique ID column and LHA1-4
6. Select the ID column and select "Unpivot other columns"
   
   
   
7. Rename the "Value" Column to "LHA Filter" or something appropriate
8. In Power BI Desktop in the "Model View" create a relationship between the 2 table using the ID columns. Make sure Cross Filter Direction is set to "Both"
   
   
   
9. Now you can use the "LHA Filter" column of the Filter Table in your slicer to filter your base table
   
   

Please let me know if this was helpful.
Thanks.
