SAP condition record query

Hi,

I have a challenge.

Actually there is an existing condition record setup at purchase org/doc type/purchasing group for Function ordering address. If i delete this condition record it will impact all the existing Po.

There is no condition record at the vendor level.

Purchase org/doc type/vendor.

But the user wants to stop the transmission if Po to the vendor but with a condition that the Po should be created only the transmission should not happen.

Please guide how to solve this
