Hi Mithun/Sid/Jay,
It seems like an authorisation issue. I checked on the QA box and I am getting an email on my outlook but the same thing is not working on DEV. I checked SU53 but there also I dont see anything that has failed authorisation. Probably will reach out to basis to generate a security trace.
Even in QA I dont see anything on the SOST eventhough an email is coming through to the outlook ..bit wierd.
Cheers,
Shyam
