The Arguments Mapping section in invoke and reply activities provides an alternative to explicitly creating multipart WSDL messages from the contents of BPEL variables.

When you use the Arguments Mapping section, an anonymous, temporary WSDL variable is defined based on the type specified by the input message of the appropriate WSDL operation.

For more information about mapping WSDL message parts, see the BPEL 2.0 Specification located at the following URL:
