Hi MathieuF ,

 

It seems that the key [action] field is missing from the data.

Please try:

Column = 
VAR _close_time = CALCULATE(MAX('Table'[created_at]),'Table'[action]="auto-close",ALLEXCEPT('Table','Table'[ID]))
VAR _result =IF('Table'[created_at]=CALCULATE(MAX('Table'[created_at]),'Table'[created_at]<_close_time,ALLEXCEPT('Table','Table'[ID])),1)
RETURN
_result

Thank you for your help, unfortunately, I have an error message:
It is not possible to determine a unique value for the "created_at" column of the "Journal" table. This can happen when a measure formula refers to a column that contains many values, without specifying an aggregation such as min, max, count, or sum to get a single result.

So I changed the query to 

 

Auto-close = 
VAR _close_time = CALCULATE(MAX('Journal'[created_at]),'Journal'[action]="auto-close",ALLEXCEPT('Journal','Journal'[id]))
VAR _result =IF(MAX('journal'[created_at])=CALCULATE(MAX('Journal'[created_at]),'Journal'[created_at]<_close_time,ALLEXCEPT('Journal','Journal'[id])),1)
RETURN
_result

 

is it good ?
Because I have no result 😞
