@Anonymous I just want to confirm how do you determine whats Line 1 and whats Line 2?

You could create a column for previous day/period COD and then another column which is difference of the 2. 

=CALCULATE(SUM[COD], DATEADD(TableName[DateField],-1,day))

OR

You could get values using the previousday function. https://msdn.microsoft.com/en-us/query-bi/dax/previousday-function-dax

OR

If you dont know the last date you could calculate previous period using 

Last=

VAR LastPeriod= CALCULATE (MAX ( FactName[DimDateKey] ),

        FILTER (FactName, FactName[DimDateKey] <> ( FactName[DimDateKey] )))

RETURN LastPeriod

@Anonymous But  COD is INT not DATE .

I need FILTER DATE and DES_COMPT_PARAD  and CALCULATE  [COD]Line 2 - [COD]Line 1  ; [COD]Line 3 - [COD]Line 2  and etc

[Anonymous]

@Anonymous I know, that is why I am using it as a sum and not the date field.

Hi @Anonymous,

What is the formula for the COD.

I also think you cant use Earlier to grab the previous information, but I need to know what COD is before giving a try to the final formula.

Hi @Interkoubess this formula COD is  :

COD = CALCULATE (min('CORRIDAS'[COD_IDENT_CORRI]);
FILTER (
'CORRIDAS';
'CORRIDAS'[DTH_INIC_CORRI] < MIN ( 'PARADAS'[DTH_INIC_PARAD] )
&& 'CORRIDAS'[DTH_FIM_CORRI] > MIN ( 'PARADAS'[DTH_FIM_PARAD] )
)
)
