Relationship between date table and data table (with null date)

Hi guys,

 

I have 2 tables INVOICE and DATE

 

Date table =

 

 ADDCOLUMNS(

calendar(min(INVOICE[INVOICE DATE]), EOMONTH(TODAY(),-1)), 

"MonthNum", MONTH([Date]),
"Month", FORMAT([Date], "MMMM"),

"Year", YEAR([Date])
)

 

 

there is a relationship between INVOICE and DATE (* ...1) by the field 'INVOICE'[INVOICE DATE] and 'DATE'[Date]

 

for a unknow reason, [INVOICE DATE] can have value NULL. Let's admit it's possible.

I always used my 'Date' table in filters, formulas, etc

 

I have some question :

1) Do you think what I have done is correct ?

2) when I put the 'Date'[Date] in the page filter, why there is null value (VIDE) in the list. There is not null value in my date table

3)I made a table with the hierarchy of the date table and the 'INVOICE'[N° Invoice] to count the number distinct of invoice, there is 49673 for date = null

but when I checked in the data tab and I filtered 'INVOICE'[Invoice Date] = null, there is only  6469 line. There is a inconsistency

Can you tell me what I did wrong ?

 

Thank you

@trungnguyen0000 , I think there are missing date, try like

 

 

 

ADDCOLUMNS(

calendar(min(INVOICE[INVOICE DATE]), EOMONTH(Max(INVOICE[INVOICE DATE]),0)), 

"MonthNum", MONTH([Date]),
"Month", FORMAT([Date], "MMMM"),

"Year", YEAR([Date])
)
