When CA XCOM Data Transport is run as a batch job (XCOMJOB) of type TYPE=EXECUTE, the external security manager performs the functions of the first two stages of security checking, as it would for any other batch job. Hence, the CA XCOM Data Transport standard security interface is not invoked. The file security user exit, however, is still invoked.
The file security user exit is invoked when receiving reports, whereas the standard CA XCOM Data Transport security exit is not.
