Ans. The erroe it shows while reload in Script as Invalid Expression.

What else have you tried?

Ans. Now i have made it like this

NCCargoRisk:

InputField SpotBnkPrice_Input;

LOAD NCCargoRisk.NumberOfDays as TotNrOfDays_CargoRisk,

         NCCargoRisk.ID as MTMID_CargoRisk,

     NCCargoRisk.ID as NCCargoRisk_Link_CargoRiskResident,

     NCCargoRisk.TCEQSECONDLEG as TCEQSecondLeg_CargoRisk,

     NCCargoRisk.SECONDLEGPRICE as SecondLegPrice_CargoRisk,

     NCCargoRisk.CARGONAME as CargoName_CargoRisk,

     Date(NCCargoRisk.STARTDATE,'$(DateFormat)') as StartDate_CargoRisk,

     Date(NCCargoRisk.ENDDATE,'$(DateFormat)') as EndDate_CargoRisk,

     NCCargoRisk.QUANTITY as Qty_CargoRisk,

     NCCargoRisk.DURATIONSECONDLEG as DurationSecondLeg_CargoRisk,

     NCCargoRisk.FREIGHTRATE as FreightRate_CargoRisk,

     Date(NCCargoRisk.PRICEDATE,'$(DateFormat)') as PriceDate_CargoRisk,

     NCCargoRisk.IFOPRICE as IFOPrice_CargoRisk,

     -(NCCargoRisk.Duration_Risk) as ExposureDuration_CargoRisk,

     NCCargoRisk.MarketValue_Risk as MarketValue_CargoRisk

FROM [$(QVDPATHTRANS)NCCargoRisk.qvd] (qvd);

left join

Load Max(PriceDate_CargoRisk,'$(DateFormat)') as PriceDate_CargoRisk1 resident NCCargoRisk;

CargoResident:

LOAD MTMID_CargoRisk,

     PriceDate_CargoRisk as PriceDate_CargoRisk_Resident,

     //MaxString(PriceDate_CargoRisk) as Max_PriceDate,

    if(PriceDate_CargoRisk = PriceDate_CargoRisk1,ExposureDuration_CargoRisk) as TD_ExposureDuration_CargoRisk,

     ExposureDuration_CargoRisk as ED_CargoRisk_Today

resident NCCargoRisk;

max( expression[, rank] )

Returns the maximum numeric value of expression encountered over a number of records as defined by a group by clause. Rank defaults to 1 which corresponds to the highest value. By specifying rank as 2 the second highest value will be returned. If rank is 3 the third highest value will be returned and so on.

Example:

Load Month, max(Sales) as LargestSalePerMonth from abc.csv group by Month;

Load Month, max(Sales, 2) as SecondLargestSalePerMonth from abc.csv group by Month;

I down totally understand your idea but try this

left join
Load date(Max(PriceDate_CargoRisk),'$(DateFormat)') as PriceDate_CargoRisk1 
resident NCCargoRisk

This will add PriceDate_CargoRisk1 field for every line in table NCCargoRisk
