I need to create a measure (DirectQuery mode) in order to calculate the number of rows that have the same values for the field [OriginType] excluding the ones that comes from the same parents. Following an example:
Parents
- Parent: A
- Parent: B
- Parent: C
Details
- Id: 1, Parent: A, OriginType: Italy
- Id: 2, Parent: B, OriginType: Italy
- Id: 3, Parent: C, OriginType: Italy
- Id: 4, Parent: B, OriginType: Italy
My representation would be:
- Parent A, Value: 3
- Parent B: Value: 2
- Parent C: Value 3
So, I need to exclude in the calculation for each parents, the details who had the same parents. How can achieve that using PowerBI Dax?
