Add column with duplicate value counts

[BiJoe]

I have a denormalized employee dimension table, and employee fact table with key columns.

Some of the employees have same roles in multiple departments, and I want to add a column to the table, showing number of times the employees have the same role. Basically counting duplicate names.

For simplicity, I need to show everything in the same table

A super simple dummy:

I have already made a separate table: 

# duplicate roles = FILTER(SUMMARIZE(dim_employee, dim_employee[Display name], "# duplicates", count(dim_employee[Display name])), [# duplicates] > 1)

but I would like to keep this as a calculated column in the fact table. It seems that I can not use the EARLIER function referenced in many similar issues, because of calling this "from" the fact table.

Happy if someone can help out.

Hi @BiJoe ,

Please try:

Count = COUNTROWS(FILTER(ALL('dim_employee'),'dim_employee'[Name]=RELATED('dim_employee'[Name])))
