Service Components Architecture (SCA) allows QoS qualifiers, such as transactions, security, and reliable asynchronous invocation, to be applied to components without requiring programming or a change to the services implementation code. WebSphere Integration Developer gives you the tools to quickly and easily compose an integrated business application that wires together components in mediation modules that can be deployed to the WebSphere Enterprise Service Bus or to WebSphere Process Server. When wiring the components, you can specify qualifiers to provide extended quality of service to the components, as well as to the clients accessing the service. Sometimes, implementations require that qualifiers are set in particular ways; Here is the explanation of the join transaction qualifier.
This scenario aims to know about how to use Transaction and Join transaction qualifiers.
For this I set Transaction qualifier as Global for implementation of mediation flow component and set join transaction as TRUE for target Interface (CRM and ERP services interfaces)
