PO Price Changes not to be allowed

Question:
Dear SAP Fans,
At present, the system is allowing to change the prices in PO after posting GR. Which system message has to give in Customization to get error message if we are going to change the price after posting GR and should allow to change the price after reversing the GR. Please give me the solution.
Thanks in advance,
