How to create a relationship between sales order and message?

[christian_swonke]

Hi all,

today when a sales order is posted via IDoc, it is possible to see this as information at sales order display:

How can I create such relationship between sales order and order source manually?

In my case order is posted via RFC call. Some parameters of the call will be stored in a Z-table.

I would like to link these record from Z-table with created sales order, now.

It would be also fine if it is just a note / info to but at least some information i.e. GUID of send message.

I had a look and I am coming all time to GOS. But I am not sure if this is the right solution...

I tried already something like this:

          CONSTANTS lc_reltype_note TYPE oblreltype VALUE 'NOTE'.

          DATA ls_object_a TYPE sibflporb.
          DATA lv_logsys    TYPE logsys.
          DATA ls_object_b TYPE sibflporb.
          DATA lv_key       TYPE string.
          DATA lv_link TYPE oblguid16.

          lv_key = |{ es_message_record-mandt } { es_message_record-company } {  es_message_record-creation_date } { es_message_record-creation_time } { es_message_record-guid }|.

          " OBJECT A - SAP DOCUMENT
          ls_object_a-instid = ev_document.
          ls_object_a-typeid = SWITCH sibftypeid( es_header-auart WHEN 'AG' THEN 'BUS2031' ELSE 'BUS2032' ).
          ls_object_a-catid  = 'BO'.

          " OBJECT B - IDOC NUMBER
          ls_object_b-instid = lv_key.
          ls_object_b-typeid = 'MESSAGE'.
          ls_object_b-catid  = 'BO'.

          CALL FUNCTION 'OWN_LOGICAL_SYSTEM_GET'
            IMPORTING
              own_logical_system             = lv_logsys
            EXCEPTIONS
              own_logical_system_not_defined = 1
              OTHERS                         = 2.
          IF sy-subrc <> 0.
          ENDIF.

          cl_binary_relation=>create_link( EXPORTING  is_object_a  = ls_object_a
                                                      ip_logsys_a  = lv_logsys
                                                      is_object_b  = ls_object_b
                                                      ip_logsys_b  = zif_base~v_sndprn
                                                      ip_reltype   = lc_reltype_note
                                          IMPORTING  ep_link_id   = lv_link ).

Link ID is created. But I can not find an information at created sales order and also not in table SRGBTBREL
