Hi JS0019 BalaSubrahmanyam,
I have raised an support case with CA regarding this Email option issue, received the below response. It may help you
"In 10.3 the licensing model moved to a transaction-consumption model.
When upgrading a license to 10.3, the "old" model is applied, and, since this is not transaction based there is no option to send email alerts regarding transaction levels.
When renewing your license, the new model will be applied - please see https://docops.ca.com/devtest-solutions/10-3/en/administering/license-administration for more information."
Regards,
Balamurugan.
