Depedent dropdown list: cannot control each line in the table view

Hello Sap Gurus,

I have set up a code in order to get dependent dropdown entries. Better said, whenever attribute X is modified you get different value for attribute Y.

The point is that I cannot control each line independently.

Once the first selection is executed as desired:

But then once I select "Outsourcing" the values are lost, like shown below.

I do believe that I miss something within the dropdown list code.

I have coded the GEP_P of the attribute LOB. Then this method is calling the event

DDLB_CLICK. This event is carrying out the set of the attribute LOB.

And then it comes the GET_V of the attribute Portfolioelement. See the code below.

DATA: current TYPE REF TO if_bol_bo_property_access.
  DATA: dref    TYPE REF TO data,
LV_PRODUCT TYPE ZDTEL00004W,
LT_DOMAIN_ENTRIES type standard table of DD07V,

wa_domain_entries type DD07V.
DATA :    lr_ddlb TYPE REF TO cl_crm_uiu_ddlb,

               it_ddlb TYPE bsp_wd_dropdown_table,

               et_ddlb TYPE bsp_wd_dropdown_table,

               ut_ddlb TYPE bsp_wd_dropdown_table,

               wa_ddlb TYPE bsp_wd_dropdown_line.
  DATA:    lv_event           TYPE string,

              lv_index           TYPE int4,

              lv_dummy           TYPE string,

              lv_one_click_lock  TYPE sysubrc.


  current = collection_wrapper->get_current( ).
Current->get_property_as_value( EXPORTING iv_attr_name = ' ZZFLD00001J ' IMPORTING ev_result = LV_PRODUCT ).

  CALL FUNCTION 'DD_DOMVALUES_GET'

    EXPORTING

      DOMNAME   = 'ZDTEL000050'

      TEXT      = 'X'

      LANGU     = sy-langu

    TABLES

      DD07V_TAB = lt_domain_entries.

  Refresh: it_ddlb.
  CASE LV_PRODUCT.

    WHEN  '01'.

      LOOP AT lt_domain_entries INTO wa_domain_entries

          AND   domvalue_l NE '0008'
          AND   domvalue_l NE '0009'.
        wa_ddlb-key = wa_domain_entries-valpos.
       wa_ddlb-value = wa_domain_entries-ddtext.
        APPEND wa_ddlb TO it_ddlb.
       CLEAR wa_ddlb.
      ENDLOOP.

    WHEN '02'.
      CLEAR it_ddlb.

              AND   domvalue_l NE '0009'.

        wa_ddlb-key = wa_domain_entries-valpos.

        wa_ddlb-value = wa_domain_entries-ddtext.

        APPEND wa_ddlb TO it_ddlb.

        CLEAR wa_ddlb.
      ENDLOOP.

      CLEAR it_ddlb.

       AND   domvalue_l NE '0008'.

        wa_ddlb-key = wa_domain_entries-valpos.
        wa_ddlb-value = wa_domain_entries-ddtext.
        APPEND wa_ddlb TO it_ddlb.
        CLEAR wa_ddlb.
      ENDLOOP.

*    WHEN OTHERS.

ENDCASE.

* Build the value descriptor reference

  CREATE OBJECT lr_ddlb

    EXPORTING

      iv_source_type = 'T'.

  Append INITIAL LINE to it_ddlb.

  sort it_ddlb by key.
  CALL METHOD lr_ddlb->set_selection_table

    EXPORTING

      it_selection_table = it_ddlb.

  rv_valuehelp_descriptor ?= lr_ddlb.


But then I have got my problem.

I need to keep the values coming from the first selection and at the same time to get other values.

Any help is welcomed.

Andrea

Hello Andrea,

I think your problem comes from this statement :

collection_wrapper->get_current( ).


You need to get your entity with the index (IV_INDEX parameter) using method FIND of the collection wrapper.
