ICCMP_BT_FOUP - How to call meth. 'DO_HANDLE_EVENT other Component/View?

Question

Dear Experts,
when changing the field CONC_KEY-BTN in view BTSHeader in component ICCMP_BTSHEAD (Interaction Record Component)
the method DO_HANDLE_EVENT of the view controller is called.
The standard coding of the method is:
method DO_HANDLE_EVENT.
* Eventhandler dispatching
    CASE htmlb_event_ex->event_server_name.
      WHEN others.
        global_event = super->do_handle_event( event           = event
                                               htmlb_event     = htmlb_event
                                               htmlb_event_ex  = htmlb_event_ex
                                               global_messages = global_messages ).
    ENDCASE.
endmethod.
The component ICCMP_BTSHEAD is used in component ICCMP_BT_INR. Also visible in component ICCMP_BT_INR is the component ICCMP_BT_FOUP (View:CREATEFOLLOWUP) used to create Follow-Up Documents like Service Tickets.
What I want to is that, if the value of the field CONC_KEY-BTN is '1', the fields of the view CREATEFOLLOWUP follow-up-document have to be not modifiable. If the value of field CONC_KEY-BTN is '2' the fields are modifiable and it is possible to create a Follow-Up Document. That is my basic requierement. Better would be if the view CREATEFOLLOWUP would not visible if the value of the field CONC_KEY-BTN is '1'. But that would be more difficult I think?
To make the fields not modifiable, I think I have to modify the Get and Set Methods of the specific Atributes. But my problem is how can I modify the above mentioned method 'DO_HANDLE_EVENT' (View: BTSHeader) so that the event 'DO_HANDLE_EVENT' of the view controller of view CREATEFOLLOWUP is called at the same time (The problem is that the 'DO_HANDLE_METHOD of view CREATEFOLLOWUP is not called when changing the field CONC_KEY-BTN of the view BTSHeader ).

Hi Oliver,
In my opinion, the logic is not to be controlled at the do_handle_event level. ICCMP_BT_FOUP is created as a component usage right? So  in the component ICCMP_BT_INR, there will be a navigation link defined with source as outbound plug of  ICCMP_BT_INR and  target as inbound plug of  ICCMP_BT_FOUP. In this outbound plug, you can fill the param IV_DATA_COLLECTION as follows:
data: lr_current type ref to if_bol_bo_property_access,
                    lr_col      type ref to if_bol_bo_col.
  lr_current = me->typed_context->YOUR CONTEXT NODE->collection_wrapper->get_current( ).
  check lr_current is bound.
  create object lr_col
    type
      cl_crm_bol_bo_col.
  check lr_col is bound.
  lr_col->add( lr_current ).
Now pass this collection to the target inbound plug.
In the inbound plug of the target, you can control the logic based on the value of the attribute field in the collection.
I think this should work.
