DFHRESPONSE is a container of DATATYPE(CHAR) that contains the response message that is processed in the response phase of a pipeline. If the message was constructed by a CICS-supplied SOAP message handler, and has not been changed subsequently, DFHRESPONSE contains a complete SOAP envelope and all its contents in UTF-8 code page.
In this situation, the normal protocol is to return DFHRESPONSE to the pipeline with the same or modified contents. Pipeline processing continues normally, with the next message handler program in the pipeline (if there is one).
Container DFHRESPONSE is also present (with a length of zero) when DFHFUNCTION contains RECEIVE-REQUEST, SEND-REQUEST, PROCESS-REQUEST, or HANDLER-ERROR.
