How to save content of the outbound synchronous proxy interface in SAP AIF?


Recently, during my last AIF project, we encountered a challenge and we wondered if it is possible to save the payload of the response message for the outbound synchronous proxy interface in SAP AIF. We found a solution, but since that time many of our colleagues working with SAP AIF encountered the same challenge and that was the reason why we decided to write this blog with our proposed solution. This blog is written in cooperation with my colleague, Krzysztof Łuka.

Problem Description

Imagine the situation when you have to configure the outbound synchronous proxy interface in SAP AIF and you have to save the content of the request and the response messages. If it comes to the content of the request message – there is no problem. You may encounter a challenge if you want to save also the response of the synchronous message.


In this blog we will focus only on the SAP AIF part – we won’t describe how to create objects on SAP PO side. We will use the ABAP report to send the request message with the message ID from ERP system to SAP PO. We expect to receive back in the synchronous response the SAP PO message key that is related to the message ID we sent in the request.

This is how sample synchronous request message looks like (with the message ID):

SAP AIF - proxy message request

And below you can see the synchronous response message with message key from the above request:

SAP AIF - proxy message response


Step by Step Instruction

First, you have to generate and activate Service Consumer that will be used in order to send the request from ERP to SAP PO.

Then you have to copy the name of the class for the generated Service Consumer. In our case, it is /INT4/CO_SI_O_GET_MESSAGE_LIST.

SAP AIF - proxy class name for processing

This class is necessary in order to create SAP AIF interface.

In next step go to AIF Customization ( /AIF/CUST transaction ) and go to Interface Development -> Define Interfaces. We will have to create new entries: one interface for the request message and the second interface for the response message.

First, create a new entry for the request message.  Type OPRGMSG001 as the interface name and 1 as the interface version.

Then Provide your Service Consumer class (in our case it’s /INT4/CO_SI_O_GET_MESSAGE_LIST ) in the class Proxy Class Outbound field and choose the proper method that will trigger sending a message to PO.

Once you provide proxy class outbound – automatically RAW Data Structure and Record Type in Raw Structure should be filled. Please provide the same structure in SAP Data Structure as was filled into RAW Data Structure and mark Move Corresponding Structures checkbox, as it is visible on the screen below:

 Outbound SAP AIF Interface determination

As a next step, we have to create another entry in Define Interface node. This time we have to do it for the Response Message.

Add a new entry with Interface Name: IPRGMSG001, interface version: 1. In Proxy Class Inbound provide the class of your Service Consumer. In our case, it is /INT4/CO_SI_O_GET_MESSAGE_LIST. Then click enter and again your Raw Data Structure should be filled automatically. Right now we are interested in the response message and because of this, we have to provide the type of the structure that is used as the exporting parameter of our class for the service consumer. In our case it is /INT4/MT_GET_MSG_LIST_RES as it’s visible on the screen below:


Use the same structure in SAP and RAW structure and mark Move Corresponding checkbox.  Please also make sure, that you have chosen specific proxy method as shown on the screen below:

Outbound SAP AIF interface definition - response

Right now we have to make sure, that proper Engine is used for both of our interfaces. Go to AIF Customization (transaction /AIF/CUST ). Then open Interface Development -> Additional Interface Properties -> Specify Interface Engines node and set for both interfaces Proxy as Application Engine, XML as Persistence Engine, AIF Index Tables as Selection Engine and AIF Application Log as Logging Engine.


The last step is to create ABAP Report, that will trigger sending the message from ERP to SAP PO.

Create a new program in transaction SE38.
In order to make this program simpler – we will hardcode the message ID that will be sent to SAP PO. We are using function module /AIF/SEND_WITH_PROXY to send the data out from ERP. We have to provide a namespace, interface name and interface version of our interface we created in AIF. In this step, you have to provide an interface used for the request message ( ‘OPRGMSG001’).

In the RESP_SAP_STRUCT changing parameter we have to provide a structure of the response, that we used in the IPRMSG001 SAP AIF interface. Then in the SAP_STRUCT changing parameter, we have to provide filled with the data structure for the request interface.

In the end, we have to use method /AIF/IF_PERSISTENCY_ENGINE~UPDATE of class /aif/cl_persist_engine_xml in order to store the response payload in SAP AIF. While using this method we have to provide details of the second interface in SAP AIF, that will store the response message.

Please see the whole code snippet for this program below:

  lc_ns          TYPE /aif/ns        VALUE 'ZDEMO',
  lc_ifname      TYPE /aif/ifname    VALUE 'OPRGMSG001',
  lc_ifver       TYPE /aif/ifversion VALUE '1',
  lc_ns_resp     TYPE /aif/ns        VALUE 'ZDEMO',

  lt_bapiret     TYPE TABLE OF bapiret2,
  lo_data        TYPE REF TO data,
  lo_xml_pers    TYPE REF TO /aif/cl_persist_engine_xml.

ls_request-mt_get_msg_list_req-message_id = 'fd9b26f7-7456-11e8-a1b1-00000069c71a'.
ls_request-mt_get_msg_list_req-archive = ' '.

IF ls_request-mt_get_msg_list_req-message_id IS NOT INITIAL.
      ns                   = lc_ns
      ifname               = lc_ifname
      ifversion            = lc_ifver
      appl_log_function    = 'AIF_SEND_WITH_PROXY'
      do_commit            = 'X'
      iv_persist_xml       = 'X'
      ximsgguid            = lv_msguid
      add_return_tab       = lt_bapiret
      resp_sap_struct      = ls_sap_resp
      sap_struct           = ls_request
      error_string         = lv_error_msg
      persistency_error    = 1
      status_update_failed = 2
      missing_keys         = 3
      interface_not_found  = 4
      transformation_error = 5
      general_error        = 6
      OTHERS               = 7.


"Persist response message
GET REFERENCE OF ls_sap_resp INTO ls_xi_data-xi_data.
ls_xi_data-msgguid = lv_msguid.
ls_xi_data-ns = lc_ns_resp.
ls_xi_data-ifname = lc_ifname_resp.
ls_xi_data-ifver = lc_ifver_resp.
CREATE OBJECT lo_xml_pers.
IF lo_xml_pers IS NOT INITIAL.
  GET REFERENCE OF ls_xi_data INTO lo_data.
      CALL METHOD lo_xml_pers->/aif/if_persistency_engine~update
          cr_xmlparse = lo_data.
    CATCH /aif/cx_error_handling_general .


Right now we can run the report. If the proxy call was successful we should see a new entry in transaction /AIF/ERR with the payload in the outbound interface OPRGMSG001 with the request message and new entry in with the payload of the response message in interface IPRGMSG001.

Below you can see the request message with the content. Message text automatically contains the information in which interface the response was processed:


In order to make sure that the response is visible we’ll go to the second interface for the response message. As you can see on the screenshot below – response message with the payload is there:

Set up interface in SAP AIF Interface Monitor ( /aif/ifmon )

Why should I set up interface in SAP AIF interface Monitor?

I can bet, that if you use SAP AIF you are familiar with AIF Monitoring and Error Handling (transaction /AIF/ERR ). Here, we can monitor and perform actions for specific interface. In addition to this transaction SAP AIF also gives us opportunity to monitor all interfaces in one place. In this blog we are going to set up interface in SAP AIF Interface Monitor (AIF/IFMON transaction). Let’s imagine the situation, that you are responsible for monitoring several interfaces. Monitoring interfaces in /AIF/ERR transaction is very helpful, although it still can be time consuming if you just want to have a quick overview what is going on in all interfaces you are responsible for.
