Block Purchase Order quantity and price based on BOM and Production quantity respectively

Question

Hi Everyone,
Hope you can help in my first project in sap b1.
My client requires that when a purchase order of subcon materials has been created it will get the 'price' from BOM row level unit price and 'quantity' from Production order row level quantity. My questions is if i there is a way to limit(block the document from addition) when does values has been changed greater than the reference document value? if ever, how?
I'm new with SAP B1 and still learning.
Im using SAP B1 9.0 PL 7 with Australian localization
Thank everyone in advance!

Hi,
Try this :
IF @transaction_type in ('A','U') AND (@OBJECT_TYPE='22')
BEGIN
If exists (SELECT t3.docentry FROM OWOR T0  INNER JOIN WOR1 T1 ON T0.DocEntry = T1.DocEntry left join POR1 T2 on T2.[U_JONum] = T0.[OriginNum] and  T0.[ItemCode] =  t2.U_SubConItem] INNER JOIN OPOR T3 ON T2.DocEntry = T3.DocEntry WHERE T1.[PlannedQty] <> T2.[Quantity] and  T1.[ItemCode]  = 'subcon' and  T3.DocEntry = @list_of_cols_val_tab_del )
Begin
SET @error = 10
SET @error_message = 'Not allowed to add more than planned'
End
End
