Hi Rick,

The Survey won't be sent when the SR is "Closed". It will always be sent out when SR is completed. The reason being following - Whenever survey is sent out user is directed to the console where he has an option to reopen the SR if he is not satisfied.

If the SR is closed then he won't be able to reopen it. More on surveys -
