Qty and Price changes in GR(PO) Document

Question

Hi All,
           One of my client want to restrict the Qty and Unit Price of GR(PO) Document in such a way where a user should not be able to change the Qty and Unit price while posting a  GR(PO) Document.
           The System what is followed now is :
           Say User raised a Purchase Order Of Qty - 5 Tons & Unit Price - 100/-
           This Purchase Order will get approved by Manager and then it gets added. Once the Purchase order gets added we post GR(PO) Document copying the same Purchase Order to the GR(PO) Document.
           Say We received the material.........Qty - 5.2 Tons...........In this case system should allow to post this quantity and add the GR(PO) Document.
           Where as when We received Qty - 6 Tons, System should not allow to post with this Quantity, (Say there should be some variance in Quantity which has to be allowed)
           Is there any settings which can be made to achive this????????????
Thanks and Regards,
Sree.

hi,
u can achieve it thru SP_TransactionNotification
try this code
--      Block GRPO if in Excess in PO Qty
IF @transaction_type IN (N'A', N'U') AND (@Object_type = N'20')
begin
     if exists (SELECT T0.BaseEntry, SUM(T0.Quantity)
     FROM [dbo].[PDN1] T0 INNER JOIN [dbo].[POR1] T1 ON T1.DOCENTRY = T0.BASEENTRY
     WHERE T0.BaseType = 22 AND T0.ItemCode = T1.ItemCode AND T0.BaseLine = T1.LineNum and T0.DOCENTRY = @list_of_cols_val_tab_del
     GROUP BY T0.BaseEntry
     HAVING (SUM(T0.Quantity) > SUM(T1.Quantity)) or sum(t0.quantity) > sum(t0.BaseOpnQty))
     begin
          select @Error = 10, @error_message = 'GRPO quantity is greater PO quantity'
     end
end
