Block item unit price from decrease in a A/R Invoice

Question

Dear experts !
How can I prevent a sales user to decrease an item unit price in an A/R Invoice for a customer for which a special price (based on quantities) was defined. The user can increase the item unit price in the A/R Invoice for that customer.
Thanks for your precious help.

Hi yves,
try below in transaction notification:
if (@object_type = '13') and (@transaction_type IN ('A', 'U'))
BEGIN
IF exists (SELECT * FROM INV1 T0  INNER JOIN ITM1 T1 ON T0.ItemCode = T1.ItemCode and  T0.[PriceList]=*2*  WHERE isnull(T0.[Price],0) <> isnull(T1.[Price],0) and t0.DocEntry=@list_of_cols_val_tab_del)
          Begin
               SET @error = 30
               SET @error_message =N'Unit Price  can`t be different than price defined Price List'     
          end
END
Change price list number (bold ) in above query to price list number you want.
you can check price list number using query
Select * from OPLN
- listnum column.
Thanks,
