Hi Deepkumar,

Dynamic configuration:

A dynamic configuration is a map containing adapter specific message attributes. You normally need to implement following API dynamicConfiguration in the message mapping:

Variable substitution:

There is another ways to get parametriced some parts of the adapters like for example the target directoy in FTP receiver without the below API, this is variable substituion.
