Question: the North American Truck Industry Part Submission Warrant has a box in the Requested Submission Level section. The box has numbers 1 through 19, with number 1 already circled. There is no explanation that I can see as to the purpose of this box. Am I correct in assuming it indicates the current PPAP submission number for that particular part (i.e. first submission, circle number 1; second submission for the same part, perhaps due to a process change, circle number 2; third submission for the same part, perhaps due to an ECO, circle number 3; etc.)? Or is it for something entirely different?
