In one of my recent projects I was asked to use one of the PI message header properties - queueid - inside the server ABAP proxy. 
It seemed like an easy task as setting serialization ID in the client proxy is relatively very simple so I started searching for some references on SDN… and could not find any.
It turns out that accessing protocol classes for provider ABAP proxies is also pretty easy but you need a different approach. Let me show you an example on how to access any XI message property in server ABAP proxies with the piece of code below:
DATA: lv_queue TYPE trfcqnam. DATA: lv_quality TYPE char4. DATA: lo_server_context TYPE REF TO if_ws_server_context, lo_xi_header TYPE REF TO if_wsprotocol_xi_header. *get the queue name and quality of service from the PI channel TRY .
lo_xi_header ?= lo_server_context->get_protocol( if_wsprotocol=>xi_header ). lv_quality = lo_xi_header->get_header_field( if_wsprotocol_xi_header=>quality_of_service ). lv_queue = lo_xi_header->get_header_field( if_wsprotocol_xi_header=>queue_id ). CATCH cx_ai_system_fault . CATCH cx_ai_application_fault . ENDTRY. |
With this piece of code you can get all possible XI header values inside the provider proxy as per attributes of the if_wsprotocol_xi_header class:

Question to you:
Have you ever needed to use any of those protocols in the ABAP server proxy ?
