Applying hold on purchase orders belonging to specific suppliers and able to manually release hold f

Hi All,

Our client has a requirement where they want to apply hold on purchase orders based on a value of DFF present at the supplier level. This is required so that they can perform an extra level of vetting for such PO's. We followed the approach of applying the hold at supplier site level using the check box-"Hold all new purchasing documents", once the hold is applied on PO's using this option, it cannot be released manually. This hold can be released only by unchecking the hold flag at site level, which is expected oracle behavior. Is there any work around
