Validation on AP invoice

Question

Hi ,
Client requires validation on AP invoice if purchase invoice value is  greater than Purchase order value.
For e.g. if purchase order is created for Item1 with 10 quantity and 100 price , total will be 1000
and purchase invoice is created as
    Item                quantity             Price           Total
1. Item1               5                      100              500
and when user creates another invoice for same order as :
    Item                quantity             Price           Total
1. Item1               5                      120              600
Here total value i.e. 500+600 =1100 but purchase value is 1000 ,this should trigger message in transaction notification script.
can any one help me with script.

Hi ,
I have this kind of SP_TN on sales order , item master and purchase master tables. And it is working.
You change the fields of your choice.
PASTE THIS CODE IN SQL SERVER
LOCATE YOUR DATABASE
EXPAND PROGRAMABILITY --- STORED PROCEDURE --- DBO.SBO_SP_TRANSACTIONNOTIFICATION
PASTE THIS CODE BELOW ADD YOUR CODE HERE
If (@object_type = '18') and (@transaction_type in ('A' , 'U'))
BEGIN
     Declare @ITEMCODE as varchar(255)     
     Declare @Qty as float
        Declare @POPRICE as float
        Declare @INVPRICE AS FLOAT
     Declare @FrstLine as int
     Declare @LstLine int
     set @FrstLine = (select min(T0.linenum) from PCH1 T0 where T0.docentry=@list_of_cols_val_tab_del)
     set @LastLine = (select max(T0.linenum) from PCH1 T0 where T0.docentry=@list_of_cols_val_tab_del)
     while @FrstLine <= @Lastline
          BEGIN
                      IF EXISTS (SELECT @ITEMCODE = PCH1.ITEMCODE , @POPRICE = POR1.PRICE FROM OPCH INNER JOIN PCH1
                      ON OPCH.DOCENTRY =
                      PCH1.DOCENTRY
                      INNER JOIN POR1 ON PCH1.BASEREF = POR1.OBJTYPE AND POR1.BASELINE = PCH1.LINENUM
                      INNER JOIN OPOR ON POR1.DOCENTRY = OPOR.DOCENTRY WHERE OPCH.DOCENTRY =   
                      @list_of_cols_val_tab_del AND PCH1.LINENUM = @FrstLine)
                      BEGIN
                              SET @InvPrice = (SELECT PRICE FROM PCH1 WHERE DOCENTRY = @list_of_cols_val_tab_del AND 
                              ITEMCODE = @ITEMCODE AND LINENUM = @FRSTLINE)
                              IF @POPRICE <> @INVPRICE THEN
                     BEGIN
                         set @error = -1
                         set @error_message = 'PO PRICE IS DIFFERENT THAN INVOICE PRICE ON LINE NUMBER' +
                                        TRIM(STR(@FRSTLINE))
                    END
                             SET @FRSTLINE = @FRSTLINE + 1
                   END
               END
END
