I think you'll need to use a Windowing Function

You replace your tables with versions that have Row Number on them

SELECT TableA.TCode,                  
    A.DCode,                 
    A.DepCode,                   
    A.ShouhinCode,                   
    B.TName AS TNameFirstRecord,                  
    C.LDepNamee AS LDepNameFirstRecord,                    
    D.ThingType AS ThingTypeFirstRecord,                  
    A.GoodsNameAS GoodsNameFirstRecord,                  
    Sum(A.Amount) AS AmountData,                 
    Sum(A.MoneyAmount) AS MoneyAmountData,                   
    Sum(A.DetailedMoneyAmount) AS DetailedMoneyAmounData,                    
    Sum(A.SummaryMoneyAmount) AS SummaryMoneyAmountData,                 
    A.POSNo                  
FROM 
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableA) A                 
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableC) C ON A.DCode = C.DCode                
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableB) B ON A.TCode = B.TCode                   
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableD) D ON A.DepCode = D.DepCode    

WHERE 
  A.RowNumber = 1 AND B.RowNumber = 1 AND C.RowNumber = 1 AND D.RowNumber = 1

GROUP BY A.TCode,                 
    A.DCode,                 
    A.DepCode,                   
    A.ShouhinCode,                   
    A.POSNo                  
ORDER BY A.TCode,                 
    A.DCode,                 
    A.DepCode,                   
    A.ShouhinCode
