Vendor Dual Control

Hi

We have created dual control for vendors and if a change is done to the identified sensitive field, business needs to confirm the vendor via FK08 to proceed with the transactions.

However though the dual control is set without confirming the vendor the business has proceed with few transactions. (FB60, F-53). They could not proceed F110 and a message was there saying to confirm vendor to proceed

I need to block all the transactions if the vendor is not confirmed. Any idea how to do it?

Thanks
