Product approval documentation and warranty terms answer different questions. One concerns a product or assembly's documented application, while the other defines contractual coverage conditions. Neither should be substituted for a property-specific roof assessment.
What to do next
Ask for both sets of relevant documents and the proposed installation details. Have the responsible professionals confirm applicability. Keep the decisions separate in the project record so an approval number is not represented as a promise of warranty coverage or future performance.
