Symptom: Unable to create an application exception in SEPM and the application exception window does not appear. The scm-server.log file may display the following exception:
SEVERE: Invalid query statement in:
com.sygate.scm.server.consolemanager.requesthandler.GetObjectHandler
java.sql.SQLException: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

You need to upgrade, preferably to 12.1.5
