Mapping Parameters
Effective in version 9.6.0, the user-defined parameter that represents a long value is named Bigint. Previously, this user-defined parameter was named Long.
Effective in version 9.6.0, parameter names that are defined in reusable transformations, relational, PowerExchange, and flat file data objects, and that begin with the dollar sign ($) are renamed to a unique name in the Model repository. However, the parameter name is not changed in the parameter file. Previously, you could use the dollar sign ($) as the first character in mapping parameter names.
