Business Process Service Variables

The Business Process Variables section of a Business Process Service editor allows you to view, create, and modify variables.

Business Process Variables can also appear in a view, depending on which you have selected to use, the view or the section.

Business process variables

Variable	Description
Interface Variables	Lists only the variables that are part of the interface to the business process. A business process can have one or more input parameters, a return parameter, no parameters, or input and return parameters. Interface variables have process-level scope. This means they are accessible throughout the business process.
Invoked Service Variables	Invoked Service variables are automatically created when you add an operation to the business process. These variables cannot be modified. Service variables have process-level scope. This means they are accessible throughout the business process.
Local Variables	Local variables are manually created by the user as needed and are visible only within the scope for which they were defined. For example, creating a new variable with a complex activity selected on the business process canvas means that the variable is accessible, in scope, only to the complex activity and activities contained within that complex activity.
