Slicer with overlapping values

047 — Thu, 17 Mar 2022 09:57:13 GMT

A newbie here. I've tried searching in the forum without luck. I'm looking to apply filter on a set of values where some of the rows may belong to mulitple categories. For example:

ItemName	Category
Apple	Fruit
Potato	Vegetable
Tomato	Both

I want to add a filter(slicer) on Category, but it should only show Fruit & Vegetable as the filter catogires. When selecting fruit, both tomato & apple should be returned, and similarly both tomato & potato when filtered on vegetable. Trying to create a new measure as the filter without luck. Can you pls help? Thanks.

Hi amitchandak

Thanks for your reply. It seems correct intutively, but I'm unable to implement it in power BI. When trying to create a relationship between 'New Table'[Category] to 'Existing Table'[Category], it says that the relationship could not be created becuase one of the columns must contain unique values. In fact, I don't even see the option of 'many-to-many' cardinality in the dropdown list. Does it require creation of an intermediate table with unique values? Thanks.

To clarify, I'm using Power BI Desktop Optimized for Power BI Report Server - May 2021.

Hi 047 ,

If your sample cannot make relationship, you can try this method.

1.Create a table with all categories, donn't make relationship between the two tables.

2. Create a measure.

Check = IF ( NOT ( ISFILTERED ( 'Table (2)'[Category] ) ), 1, IF ( ISFILTERED ( 'Table (2)'[Category] ) && ( MAX ( 'Table'[Category] ) = SELECTEDVALUE ( 'Table (2)'[Category] ) || MAX ( 'Table'[Category] ) = "Both" ), 1 ) )

3.Put the new category table in the slicer, and put the measure in the ItemName visual filter, select the value is 1.

Get the correct result.

I attach my sample below for reference.

Thanks Kalyj.

Sorry for my late reply. I was a bit preoccupied and couldn't check your solution. As you've already tested, your solution works well. Sorry for not being clear enough with my requirement, but my case is a little bit different.

First, my Category slicer is set to single select, so I modified the measure to exclude the check for isfiltered.

Check2 =
IF( MAX ( 'Table'[Category] ) = SELECTEDVALUE ( 'Table (2)'[Category] ) || MAX ( 'Table'[Category] ) = "Both",1,0)

But, In my case, there're multiple visuals on the same/different pages of the report. I was unable to set the measure Check or Check2 as a page/report level filter. Any suggestions?

What I'm doing as a temporary workaround is to duplicate all records where category is 'both'. One of the duplicated rows has Category set as 'Vegetable' & the other row as 'Fruit'. Thanks
