MPN materials and inspection lot creation

Dear all, We are planning to use MPN process for sourcing for vendors from different manufacturers. I have seen that this is possible in the scenario with inspection types with same inspection origin(01) and also saw some posts here.

We have different status maintained for Q Info record in status profile and user manually select a status. Based on the selection of status the corresponding inspection type will be triggered. My question is as we are creating Q info record based on MPN material , do we have to create inspection plans on MPN material level or main material level?

I understood that we can create different inspection plans for different inspection types with different usage for same vendor .do we have to link vendor in Inspection plan level ( in material assignment tab).Currently we are not using this field. Thank you for your time.

Best regards
