Problem with formulating dates and holidays

Hi,

So ALL can do some strange things, I would suggest first splitting up your formula into different measures first to first try and identify what is going wrong, as my guess is the ALL is causing it to ignore your second commented out filter, I would also try the following:

Bad Daily Goal =

Divide(
            SUMX(filter(ALL('Date'),
                    'Date'[Month] = month(SELECTEDVALUE('Date'[DateValue])) &&
                    'Date'[Year] = year(SELECTEDVALUE('Date'[DateValue])) 
                    ),
                    Calculate('PresupuestoVentas_All_SoloDaily'[PresupuestoVentas_All_SoloDaily],
                                Filter('Holiday Delegations', 
                                        'Holiday Delegations'[pkDayKey] = selectedvalue('Date'[DateValue]) &
                                        'Holiday Delegations'[pkCodDelegation] = SELECTEDVALUE('Delegations All'[pkCodDelegation]) &
                                        'Holiday Delegations'[Es_Laborable] = "S"     
                                        )
                            )
                ) ,
        Calculate([Total Business Days Daily Sales - All],
                    Filter(ALL('Date'),
                    'Date'[Month] = month(SELECTEDVALUE('Date'[DateValue])) &&
                    'Date'[Year] = year(SELECTEDVALUE('Date'[DateValue])) 
                         )   
                )
                ,0)

It may also help just filtering to the holidays before anything else
or lastly you can also try ALLEXCEPT (less likely to work as I do not know the table relationships):

Bad Daily Goal =

Divide(
        Calculate('PresupuestoVentas_All_SoloDaily'[PresupuestoVentas_All_SoloDaily],
                    filter(ALLEXCEPT('Date','Holiday Delegations'[pkDayKey],'Holiday Delegations'[pkCodDelegation],'Holiday Delegations'[Es_Laborable]),
                    'Date'[Month] = month(SELECTEDVALUE('Date'[DateValue])) &&
                    'Date'[Year] = year(SELECTEDVALUE('Date'[DateValue])) 
                    ),
                    Filter('Holiday Delegations', 
                            'Holiday Delegations'[pkDayKey] = selectedvalue('Date'[DateValue]) &
                            'Holiday Delegations'[pkCodDelegation] = SELECTEDVALUE('Delegations All'[pkCodDelegation]) &
                            'Holiday Delegations'[Es_Laborable] = "S"     
                            )
                ),
        Calculate([Total Business Days Daily Sales - All],
                    Filter(ALL('Date'),
                    'Date'[Month] = month(SELECTEDVALUE('Date'[DateValue])) &&
                    'Date'[Year] = year(SELECTEDVALUE('Date'[DateValue])) 
                         )   
                )
                ,0)
