Hide Purchase Price info

Question

We are looking for a way to hide the purchase order price from some internal employees. We are looking at two possible options.
1. Use security to restrict access to a specific purchasing group in all purchasing transactions. Use authorization object S_TABU_DIS to prevent users from viewing tables with class MA. Unfortunately I can still see purchase order price in MB51, MIGO, MCE* transactions. Is there anyway to restrict a set of users from seeing purchase order price in MM and the downstream accounting docs?
2. Create a PO for free goods. Pay the vendor via a manual journal entry. This solution will prevent the end user fro seeing the actually purchase order price as the manual journal entry will not be tied directly to the PO.
Is there any other way to hide the purchase price from internal users? I am not confident that we can have a robust enough security policy that a user can not find a report or transaction that includes the price. We do not like the second solution as it requires a lot of manual work and will make the standard cost for the material inaccurate.
Your help is much appreciated.

Dear Thomas,
Yes there is a provision in SAP for hiding PO price to specific users. Follow the steps as under.
1. Execute tcode OMET.
2. Create Function Authorization : NP (any name u wish to give) enter description as "No prices display auth."
3. Select FieldSel. as "$DE2  Without displaying price"
4. Then Save.
5. Now you need to maintain user parameter EFB with value NP in user maintainance SU01/SU3. Maintain this parameter in ID of the users whome you do not want to display PO price.
Thats all you can do for hiding PO price to specific users. I m sure it will fulfill your requirement.
Note:
1. Do not select any other option as it may affect other Std functionality.
2. After maintaining this parameter the particular user is unable to view PO conditions.
