Date Difference between 2 different tables

[koray]

Hello,

I want calculate Date Difference between 2 different tables. I think I did but i have two problem.

1-) that but it gives wrong result when calculating same days.

I use this: 

Miro Tarih = DATEDIFF(MAXX(RELATEDTABLE(Miro),Miro[Fatura Tarihi].[Date]),'Detailed DED Analysis'[DocumentDate].[Date],DAY)

2-) I also want to do the subtraction in reverse, but I couldn't.

I want the calculate to be like this: Detailed DED Analysis'[DocumentDate] - Miro[Fatura Tarihi]

not like this: Miro[Fatura Tarihi] - Detailed DED Analysis'[DocumentDate]

Regards,

Hi @koray 

Try this if there is a relationship based on the DocumentNumber between those 2 tabels:

Miro Tarih =
LOOKUPVALUE (
    Miro[Fatura Tarihi],
    Miro[DocumentNumber], Detailed DED Analysis[DocumentNumber]
)
    - MAX ( Miro[DocumentNumber] )

Hello @VahidDM 

Thank you for reply. 
It did not happen. Or I did something wrong 😞

Miro Tarih2 =

LOOKUPVALUE (Miro[Fatura Tarihi],Miro[Fatura Tarihi],'Detailed DED Analysis'[DocumentDate]

)

-MAX('Detailed DED Analysis'[DocumentDate])

@koray 

Each Document Number in Miro table has many dates, which onr do you want to use in the calculation?

Hi @VahidDM 

I want the calculate to be like this: Detailed DED Analysis'[DocumentDate] - Miro[Fatura Tarihi]

(first Fatura Tarihi dates) that is, the earliest "Fatura Tarihi" belongs to that Document number. @VahidDM 

like this:

Try this:

Measure = DATEDIFF(max('Detailed DED Analysis'[DocumentDate]),max(Miro[Fatura Tarihi]),DAY)

Output:

Thank you so much @VahidDM 
Seems to be working fine. But I couldn't understand why it gives a different result in the crossed out one in the picture below.

@koray 

Because of the different aggregation you set for that column (for e.g. Earlier) and the MAX formula you used in the measure.

Appreciate your Kudos!!
