Asynchronous request object handle

OpenEdge maintains an asynchronous request object for each asynchronous request, which maintains the status of the request, including whether and how it has completed (successfully or unsuccessfully). The handle to this asynchronous request object is available to the mainline program and to the event procedure for an asynchronous Web service request in the same way as for an asynchronous AppServer request. The Web service server object handle maintains its own chain of pending asynchronous request object handles (FIRST-ASYNC-REQUEST and LAST-ASYNC-REQUEST attributes), and the PROCEDURE-NAME attribute on each asynchronous request object handle returns the name of its Web service operation as it returns the name of the remote procedure executed for an asynchronous AppServer request.

Attribute	Meaning for Web service requests
ERROR	Returns TRUE within the context of the event procedure when: You invoke the RETURN ERROR statement within the context of an associated SOAP response header callback procedure. A SOAP fault is returned for the asynchronous Web service request.
NEXT-SIBLING and PREV-SIBLING	Maintains a chain of asynchronous request object handles for all pending asynchronous requests invoked in the same Web service
PERSISTENT-PROCEDURE	Returns a handle to the procedure object bound to the Web service port type
PROCEDURE-NAME	Returns the name of the Web service operation invoked asynchronously
QUIT	Always returns FALSE for an asynchronous Web service request
SERVER	Returns a handle to the server object for the Web service where the asynchronous request is executed
