Adding supplier text during runtime in SC

Question

Hi Experts,
I am doing an enhancement to add supplier text in describe requirement screen. When the item is added to the shopping cart I am doing enhancement at the end of the method in class /SAPSRM/CL_CH_WD_DODM_SC_I_DSC
method /SAPSRM/IF_CLL_DODM_SC_I_DESCR~ADD_DESCRIBED_ITEM_TO_TABLE to add the supplier text to shopping cart item.
There is a standard code in method /SAPSRM/IF_CLL_DODM_SC_I_DESCR~ADD_DESCRIBED_ITEM_TO_TABLE which adds the internal note to the item is like
* set Data to pdo-object
    "prepare call
    lo_pdo_sc ?= mo_pdo.
    "call
    TRY.
        lo_pdo_sc->add_item( EXPORTING is_item   = ls_pdo_item
                                       iv_uname  = sy-uname
                                       iv_account_for_ess = iv_ess
                             IMPORTING es_return = ls_pdo_item_control
                             CHANGING  co_message_handler = mo_pdo_message_consumer ).
* Add internal note as longtext
        wd_main_node = mon_cll_set_facade->get_main_node( ).
        wd_child_node = wd_main_node->get_child_node( name = 'INTERNAL_NOTE' ).
        wd_child_node->get_attribute( EXPORTING name = 'INTERNAL_NOTE' IMPORTING value = lv_internal_note ).
        TRY.
            CALL METHOD lo_pdo_sc->/sapsrm/if_pdo_do_longtext~update_longtext
              EXPORTING
                iv_p_guid          = ls_pdo_item_control-guid
                iv_tdid            = 'NOTE'
                iv_tdspras         = sy-langu
                iv_tdformat        = 'X'
                iv_text_preview    = lv_internal_note
*              CHANGING
*                EV_CHANGED         = LV_CHANGED
*    CO_MESSAGE_HANDLER =
          CATCH /sapsrm/cx_pdo_abort INTO lx_pdo_abort.
            mo_cll_message_handler->set_abort( io_pdo_abort_exception = lx_pdo_abort ).
        ENDTRY.
* update
        mo_pdo->submit_update( CHANGING co_message_handler = mo_pdo_message_consumer ).
* because view will be invalidated: clear the mapper reference from the bo_mapper
        mo_parent_bo_mapper->deregister_mapper( io_mapper = me ).
* refresh whole application because e.g. Total value of sc has maybe changed.
* updates were performed a step before
        mo_parent_bo_mapper->fire_event_refresh( iv_perform_updates = abap_false ).
* close window
        lo_window_controller = mo_wd_view_controller->get_embedding_window_ctlr( ).
        lo_window = lo_window_controller->get_window( ).
        lo_window->close( ).
        ev_close_window = abap_true.
I have done the similar code for updating the long text changing the tdid to HTXT but since I am not adding the item to the SC I have just implemented the update_longtext method. The text is being added to the buffer but not saved and reflected in SC.
I have implemented the following in the enhancement.
CALL METHOD lo_pdo_sc->/sapsrm/if_pdo_do_longtext~update_longtext
              EXPORTING
                iv_p_guid          = ls_pdo_item_control-guid
                iv_tdid            = 'HTXT'
                iv_tdspras         = sy-langu
                iv_tdformat        = 'X'
                iv_text_preview    = lv_internal_note
* update
        mo_pdo->submit_update( CHANGING co_message_handler = mo_pdo_message_consumer ).
What should I do to save the changed text?

hello srinivas,
I am not sure about long text but i have updated PO item in run time.
Please find the code below may be it will be helpful for you.
Try the same for SC.
DATA:    lo_bom_po                  TYPE REF TO /sapsrm/if_cll_bom_po,
              lo_bo_po_adv             TYPE REF TO /sapsrm/cl_pdo_bo_po_adv,
              lo_pdo                         TYPE REF TO /sapsrm/if_pdo_base,
              lo_task_factory           TYPE REF TO /sapsrm/if_cll_taskcon_factory,
              lo_task_container        TYPE REF TO /sapsrm/if_cll_task_container.
DATA :  lx_pdo_no_authorization TYPE REF TO /sapsrm/cx_pdo_no_authorizatio,
             lx_pdo_wrong_mode TYPE REF TO /sapsrm/cx_pdo_wrong_mode,
             lrcl_current_controller  TYPE REF TO if_wd_controller,
             lrcl_message_manager     TYPE REF TO if_wd_message_manager.
lo_task_factory = /sapsrm/cl_ch_wd_taskcont_fact=>get_instance( ).
  IF lo_task_factory IS NOT INITIAL.
    lo_task_container = lo_task_factory->get_task_container( ).
    IF lo_task_container IS NOT INITIAL.
      lo_bom_po = lo_task_container->get_bom_po( ).
      lo_pdo = lo_bom_po->/sapsrm/if_cll_bo_mapper~get_pdo( ).
      lo_bo_po_adv ?= lo_pdo.
    ENDIF.
  ENDIF.
TRY.
        CALL METHOD lo_bo_po_adv->/sapsrm/if_pdo_bo_po~update_item
          EXPORTING
            it_item = lt_pd_item.
      CATCH /sapsrm/cx_pdo_no_authorizatio INTO lx_pdo_no_authorization .
        RAISE EXCEPTION TYPE /sapsrm/cx_pdo_abort EXPORTING previous = lx_pdo_no_authorization.
      CATCH  /sapsrm/cx_pdo_wrong_mode INTO lx_pdo_wrong_mode .
        RAISE EXCEPTION TYPE /sapsrm/cx_pdo_abort EXPORTING previous = lx_pdo_wrong_mode.
    ENDTRY.
    " don't forget to submit the changes
    lo_pdo->submit_update( ).
