An

operation

is the command that is run when a Web service activity executes. A set of related operations is bundled in a port type in a WSDL. BPEL activities such as receive, reply, and invoke include operations.

You can select

Navigate > Open Operation

and use the

Open Operation

dialog to locate an operation within a WSDL. Start typing the name of an operation from a workspace WSDL to display a list of auto-completed names. The target namespace of the WSDL is displayed in the dialog. Double-click an operation to open the WSDL and highlight the operation.
