Calculated Column & Référence to one line.

Hi everyone, 

I'm a fresh user of Power BI (less than 6 months experience) but OK in Excel.

I have some dashboard that I would like to move from Excel to Power BI but still struggling with some calculated rows.

In Excel, I have a moving mean  (or sum) calculated for each different people with basics formula like : 

SUMIFS((Total Distance]; [Date]; "<="[@Date];[Date];">"&[@Date]-7;[Player];[@Player])

I switched in Power Bi with a simple : 

Calculate(sum([Total Distance)]; Datesinperiod (...) ; 

But I don't know what to add to replace my player filter [@Player]...

Anyone could help me ?

All the best,

Mathieu.
