This parameter type uses the return value of a web service
call as an input.
On the Output tab, all return values of the web
service that have been selected in the upper area of the dialog will be
shown. This means that return values from previously submitted calls
can be selected as inputs as well.
Input and output parameter types must correspond to one
another. The priority of the calls, which controls the sequence of
requests, must be taken into account with the parameter type Return
Value by the web service.
