Alert navigation is working but without any data in the views

Question

Hi Experts,
                   Currently I am working with CRM 2007(6.0), I am facing issues regarding the Alert navigation. Below are my comments.
1. Created an alert with navigation objcet specified as FICAACCBALANCEDISP:B for Account balance display
2.Created a rule policy with required condition.
3.During the confirmation of Business partner alert is getting displayed in the alert information bar along with hyper link for the alert.
4. When i clicked on the navigation link it is navigating to the account balance display page but with out any data.
5. If i Check the account balance from the l-shape navigation, i could find the data in the respective views.
Please provide your suggestion why when i try to navigate to the accound balance display by clicking on the hyper link it is not displaying any data?. Thanks
Contributions will be highly appriciated.
Regards,

Hello Lakshmana,
Fact-gathering services are OK to get data used in alert configuration, but I also observed that alert framework does not allow to pass key of navigation entity when alerts are clicked for navigation.
This is why you should use an action-handler service instead ! Check existing classes implementing interface if_crm_smf_action_handler. There are some delivered by SAP that produce alerts.
In your own one class implementing that interface, you can control what data is passed during navigation, like in following code snippet:
  DATA:
    lr_alert_srv            TYPE REF TO if_crm_ic_5x_ext_alert_srv,
    lr_event                TYPE REF TO cl_crm_ic_event,
    lv_alert_id             TYPE        crm_ic_alert_id,
    lv_message              TYPE        string,
    lv_event_name           TYPE        crm_ic_event,
    lv_tooltip              TYPE        string,
    lv_navlink              TYPE        crm_ic_navbar_navlink,
    lv_delay                TYPE        i.
  connect to alert singleton
    lr_alert_srv ?= cl_crm_ic_5x_ext_alert_srv=>if_crm_ic_5x_ext_alert_srv~get_instance( ).
    IF lr_alert_srv IS BOUND.
      lv_event_name = 'ContactStarted'.
    alert message
      CONCATENATE text-001 lv_ticket_number INTO lv_message SEPARATED BY space.
      IF lv_ticket_guid IS NOT INITIAL.
      clickable link
        CONCATENATE 'BT116_SRVTK:B:BT116_SRVTK:' lv_ticket_guid INTO lv_navlink.
        lv_tooltip = text-002.
      ELSE.
      ticket does not exist
        lv_tooltip = text-003.
      ENDIF.
    trigger alert
      lr_alert_srv->trigger_alert(
                      iv_alert_id   = lv_alert_id
                      iv_message    = lv_message
                      iv_event_name = lv_event_name
                      iv_tooltip    = lv_tooltip
                      iv_navlink    = lv_navlink
                      iv_delay      = lv_delay     ).
     alert click is handled by CL_CRMCMP_I_HIDDENVIEW_IMPL->NAVIGATE_ALERT
    ENDIF.
  ENDIF.
Hope this could help you
Best regards
