You'll need to provide more details, such as table structure.

Ok this is the Table I created

CREATE TABLE TRANSACTIONS_ORDERDETAILS
(
PurchaseOrderID int Identity (2,2) primary key nonclustered,
Orderdate DATETIME DEFAULT (GETDATE()),
CONSTRAINT CHECK_ORDERDATE CHECK (ORDERDATE < DATEADD(dd,DATEDIFF(dd,0,GETDATE()),1)),
QuantityOrdered varchar (50),
CONSTRAINT check_ID5 CHECK (QuantityOrdered > 0 ),
QuantityReceived INT null,
CONSTRAINT check_ID6 CHECK (QuantityReceived >= 0 ),
UnitPrice Money ,
CONSTRAINT check_ID7 CHECK (UnitPrice > 0 ),
OrderStatus varchar (50) not null,
CONSTRAINT check_ID10 CHECK (Quantityreceived <= QuantityOrdered ),
ItemID int,
EmployeeID int,
ReceivingDate datetime null,
CONSTRAINT check_ID8 CHECK (ReceivingDate > Orderdate )
)

Best Regards.

* Calculation of the total cost for a Particular Order.
Apply GROUP BY over PurchaseOrderID field and apply SUM over (UnitPrice * QuantityReceived )


* Calculation of the total of all the orders placed by a particular Employee in a Particular Month
GROUP BY on EmployeeID and DATEDIFF(mm,0,orderdate) and apply SUM over (UnitPrice * QuantityReceived )
