VF01/VF02 Suppress Output - User exit/Routine?

Folks,

We have a requirement to suppress outputs during invoice creation(VF01/VF02) if a certain pricing procedure is being used. Does anyone know of a routine, user exit where we can supress the output for a particular scenario.

Since this criteria is specific to a pricing procedure, we cannot use output determination to use condition types. The outputs should get generated for all situations besides when a particular pricing procedure is in use.

Please let me know.

Thanks,

Rajesh
