Show user picture at Fiori Launchpad

In some presentation from SAP I saw a little user picture on the right top corner near the name.

Today I invest a little bit time to  find how does it works.

In the default the picture is show from the SAP JAM Account :

Social Media Integration – User Interface Add-On for SAP NetWeaver – SAP Library

But in our company we have no SAP JAM.

So I searched for a solution to integrate a image from the hcm system.

The solution I found in two default classes:

Enable JAM Integration

Class CL_SMI_COLLAB_PLATF_CHECKER

Method: IS_JAM_CONFIGURED

Gateway Class for the image (GETSTREAM):

Class : CL_SMI_ODATA_SRV_702

Method : GET_STREAM

First I have enhanced the class CL_SMI_COLLAB_PLATF_CHECKER in the method IS_JAM_CONFIGURED.

“return True”

METHOD IOW_YCL_SMI_COLLAB_PLATF_CHEC~IS_JAM_CONFIGURED.
*"------------------------------------------------------------------------*
*" Declaration of Overwrite-method, do not insert any comments here please!
*"
*"class-methods IS_JAM_CONFIGURED
*"  returning
*"    value(RV_IS_JAM_CONFIGURED) type ABAP_BOOL .
*"------------------------------------------------------------------------*
rv_is_jam_configured = abap_true.
ENDMETHOD.

Next I enhanced the class CL_SMI_ODATA_SRV_702

if iv_source_name = 'Member' and it_navigation_path is not initial and lines( it_navigation_path ) = 1.
     field-symbols <ls_navigation_segment> like line of it_navigation_path.
     read table it_navigation_path index 1 assigning <ls_navigation_segment>.
     if <ls_navigation_segment>-nav_prop = 'ProfilePhoto'.
*      " Obtain the member's id.
*      data lv_member_id type cl_sm_integration_mpc_ext=>ts_member-id.
*      lv_member_id = get_first_key( it_key_tab ).
       " Get the member's profile photo.
       field-symbols <lr_stream> type /iwbep/if_mgw_appl_srv_runtime=>ty_s_media_resource.
       create data er_stream type /iwbep/if_mgw_appl_srv_runtime=>ty_s_media_resource.
       data lv_picture type XSTRINGVAL.
              CALL FUNCTION 'YFIORI_GET_IMAGE' DESTINATION 'HCM_SYSTEM'
         IMPORTING
           EV_PICTURE       = lv_picture
                  .
       assign er_stream->* to <lr_stream>.
    <lr_stream>-mime_type = 'image/jpg'.
             <lr_stream>-value  = lv_picture.
*      move mo_smi_odata_srv_helper->get_member_profile_photo( lv_member_id ) to <lr_stream>.
     endif.
   else.
*    raise_operation_not_supported( ).
endif.

On the HCM System I wrote a little function to get the user image and return this image as xstring to gateway system.
