Tableau to Power BI function

Hi Raks,

For calculating running total based on date you need to create calander table separately and create relationship. 

The final measure looks like below.

IF ( avg(INT([Fiscper])) <avg( INT([Current Fiscper]) ),

sum([Act Inv]),

CALCULATE(SUM([Inventory National]), Filter(all(Table[Date]),Table[date] <= Max(Table[date]))

Appreciate a Kudos! ‌‌
If this helps and resolves the issue, please mark it as a Solution! ‌‌
