It's not easy to identify which workflow is open in Process Assembly.
we see the workflow for example RM.DEFAULT.THT_WORKFLOW.807 but don't really how it is naming.
From Release Automation version 9, the naming conventions for Application Workflow follow rule below:
Application_folder_name is the name of application folder.
WorkFlow_name is name of workflow
Application_ID is the unique ID of each Application.
The Application ID can be easily seen from the URL in web browser when you open the Application, for example: http://xxxxx-i17327:8080/awi/#bond-p/applications/dashboard&oid=807~JMZ -> Application ID is 807.
I hope this helps you easier to identify the Workflow.
