Hello Mr Craig,
I never said that you don't need to activate the inspection type with variance 1 for inspection lot generation. That is one mandate thing need to be done. What I said that out of two inspection type (lets say with variance 1 and 2), preferred need to be set for 2 if inspection lots are required, else system would pick that with variance 1 if not set for anyone, provided both are active!!
At least for your version that debunks the folks that have claimed to me that you don't have to activate the 01 variant for the inspection type.
Kindly review what F1 document for preferred box states (point no 2 and 3 under dependencies),
Preferred Inspection Type
Use
If you set this indicator, the system creates preferred inspection lots with this inspection type for the corresponding inspection lot origins.
Dependencies
You can define several inspection types for an inspection lot origin in Customizing and activate them in the inspection setup for the material. The system chooses an active inspection type during inspection lot creation based on the following order:
1. The inspection type is determined using a special rule. It can be determined, for example, for inspection lot origin 01 from the quality information record, or for inspection lot origin 03 from the order type.
2. If there is no special rule and the indicator "Preferred inspection type" is set, the system chooses this preferred inspection type for the corresponding inspection lot origin.
3. If the indicator "Preferred inspection type" is not set for any of the inspection types for the inspection lot origin, the system chooses the inspection type that was assigned to the inspection lot origin in Customizing as variant 01.
If the chosen inspection type is not active, no inspection lot is created
