Hi,
As mentioned earlier, you need to pass the host name and port of the second system. If the application name is same, pass the same application name.
DATA: lv_url TYPE string,
       lv_host TYPE string,
        lv_port TYPE string,
        lv_protocol TYPE string.
  CALL METHOD cl_wd_utilities=>construct_wd_url
    EXPORTING
      application_name = 'ZWD_APPL_NAME'
      in_host          = lv_host   " host name of second system (X09)
      in_port          = lv_port    " port of second system
      in_protocol      = lv_protocol  " protocol of second system
*      in_parameters    = lt_parameters
      namespace        = 'sap'
    IMPORTING
      out_absolute_url = lv_url.
To get the Host, Port and Protocol of second system, wrap the below code in a Function Module(RFC) in X09 and call this in X01 and then pass them to the cl_wd_utilities=>construct_wd_url as mentioned above
CALL METHOD cl_http_server=>if_http_server~get_location
    IMPORTING
      host         = host
      port         = port
      out_protocol = out_protocol.
hope this helps,
