When you build and upload a subscription triggered process, Process Engine uses the default Integration Server connection alias, based on the message provider configured in Integration Server. The default connection alias for Broker is IS_BROKER_CONNECTION. The default connection alias for Universal Messaging is IS_UM_CONNECTION. When you change the default connection alias, you must reload the WmPRT package in Integration Server Administrator.

When you create a custom IS connection alias, you must set it as the default connection alias. Process Engine always uses the default IS connection alias.
