Thank you. I have raised an SR as it crossed 75 days. So that does not require any documentation. They require documentation only when you want to expedite. The expedite criteria is on the Isis website. Also just a tip..when you raise an SR, do not ask for case out of normal processing times, ask for opening it as it passed 75 days..if you open it under processing times, I think they reject it as the processing time frame is April 2017 .I have observed that people get confused.good luck with yours!
