DAX equivalent of Tableau Formula

[Yashi]

Can someone explain what the formula below in Tableau does and help me convert it to PowerBI DAX. 

DATEDIFF('day',MAX({EXCLUDE [date_of_observation] : MAX(Planted Date )}),MAX([date_of_observation]))

Hi @Yashi ,

This Tableau is mainly calculate the difference of max[date_of_observation] and Max[planted Date](Exclude [date_of_observation]).

The following DAX might work for you:

Measure2 = 
  var _InDate = MAX('Table'[Invoice Date])
  var _DuDate = MAX('Table'[Due Date])
  RETURN
     IF(_DuDate <> MAX('Table'[Invoice Date]) , 
    DATEDIFF(_InDate,_DuDate,DAY),
    BLANK())

The final output is shown in the following figure:
