Validation If unit price of GRPO is different from PO

Question

Hi,
I  am trying to assign 1 validation for scenario mentioned in the subject. The validation which i have tried is showing me error even if i have not changed the unit price at the GRPO level.
IF @transaction_type IN (N'A', N'U') AND
(@Object_type = N'20')
begin
if exists (SELECT T1.[Price], T3.[Price] FROM OPDN T0  INNER JOIN PDN1 T1 ON T0.DocEntry = T1.DocEntry
INNER JOIN OPOR T2 ON T2.DocEntry=T1.BaseEntry  INNER JOIN POR1 T3 ON T2.DocEntry = T3.DocEntry
WHERE T1.ItemCode=T3.ItemCode And T1.[Price]<>T3.[Price])
Begin
select @Error = 10, @error_message =
'UNit price is different from PO'
Regards-
Monica.

Hi Mona
Try with this : 
If @object_type='20' AND @transaction_type = 'A'
BEGIN
If Exists
(SELECT TRUE
   FROM PDN1 T0 INNER JOIN POR1 T1
         ON T0.BaseEntry=T1.DocEntry and
            T0.BaseLine=T1.LineNum
   WHERE T0.DocEntry = @list_of_cols_val_tab_del
      AND (T0.BaseRef=' ' or T0.BaseRef IS NULL)
     AND T0.Price!=T1.Price)
Begin
SELECT @error = 1,
@error_message = 'Price is different'
End
END
The logic is same but becasue of data coming into the system . Also check in your database
select * from POR1
Hope this helps
