CICS backtrace and PurePath

The following figure shows a CICS Service-Level Backtrace that was started by an MQ call. The message was initially put into the queue by a Java application, so the CICS PurePath has been linked to the Java PurePath by MQ tagging. You can see all the way back to the Mobil App.
