Power BI slicer OR condition - powerbi

Question

The interaction between two slicers in Power BI gives me output with AND condition.
Example: If I selected the year 2020 and company ABC, the output would be all the data from company ABC in the year 2020.
But I want the two slicers to work with OR condition.
I have used this Dax
Include = (MAX(Table1[Column1]) = SELECTEDVALUE(Col1[Column1])) +
(MAX(Table1[Column2]) = SELECTEDVALUE(Col2[Column2]))
But the problem with above Dax I have not selected anything in slicer ( ALL by default) it is showing me a blank visual. What am I doing wrong?

Answer 1

let me guess you have a table "or_slicer_main_table" with Year, Company and some other columns. Now create 2 new table where the first one will contain the distinct list of Year from table "or_slicer_main_table" and the second one will contain distinct Company list from that same table.
New custom Table 1:
or_slicer_year_list =
SELECTCOLUMNS(
'or_slicer_main_table',
"YEAR", 'or_slicer_main_table'[year]
)
New custom Table 2:
or_slicer_company_list =
SELECTCOLUMNS(
'or_slicer_main_table',
"company", 'or_slicer_main_table'[company]
)
Do not establish any relation between those 3 tables.
Step-1: Create Year slicer using the newly created "or_slicer_year_list" table.
Step-2: Create Company slicer using the newly created "or_slicer_company_list" table.
Step-3: Create these following 5 measures in your table "or_slicer_main_table"
1.
year_current_row = max('or_slicer_main_table'[year])
2.
year_selected_in_slicer = SELECTEDVALUE(or_slicer_year_list[YEAR])
3.
company_current_row = max('or_slicer_main_table'[company])
4.
company_selected_in_slicer = SELECTEDVALUE(or_slicer_company_list[company])
5.
show_hide =
if(
[year_selected_in_slicer] = [year_current_row]
|| [company_selected_in_slicer] = [company_current_row],
1,
0
)
Now you have all instruments ready for play. Create your visual using columns from the table "or_slicer_main_table"
Final Step: Now just add a visual level filter for the measure "show_hide" and set value will show only when "show_hide = 1".
The final output will be something like below image-

Can you try using "IN VALUES" instead of "SELECTEDVALUE"
So your DAX should be
Include = (MAX(Table1[Column1]) IN VALUES (Col1[Column1])) +
(MAX(Table1[Column2]) IN VALUES (Col2[Column2]))
SELECTEDVALUE function returns the result only if single value is selected in slicer in case of multiple selection it will return Blank(). Thats in the case when nothing is selected (which is similar to all selected) has multiple values in set and so SELECTEDVALUE fucntion will return Blank(). This can be handled by using "IN VALUES" function which can return a set of all selected values.
