Get the value from another node.

Question

Hi, expert
In the component BT131I_SLS , I create a enhanced attribute in the node: BT131I_SLS/Details BTADMINI
Then i define the GET-V method to create a search help for the attribute.
Now , i want to pass a BP number to the search help function to filter the data.
We need to get the BP number as below:
When create a order, we input the product id ,
then there will be a popup window , we can choose  a vendor in the window.
The vendor number is the value which we want to pass to the search help.
How can i do that ?
Thanks.
Oliver.

Answer 1

Hi , expert
Can i use the 'get_related_entities' to get the value I need?
I think maybe i can use the method to get the value from another view which is not in my component.
Now I write codes in the GET-V method, as below:
method GET_V_ZZZFLD000011.
  DATA:
    LS_MAP    TYPE IF_BSP_WD_VALUEHELP_F4DESCR=>GTYPE_PARAM_MAPPING,
    LT_INMAP  TYPE IF_BSP_WD_VALUEHELP_F4DESCR=>GTYPE_PARAM_MAPPING_TAB,
    LT_OUTMAP TYPE IF_BSP_WD_VALUEHELP_F4DESCR=>GTYPE_PARAM_MAPPING_TAB.
  DATA: LV_PARTNER_NO TYPE CRMT_PARTNER_NUMBER.
  data: lr_current TYPE REF TO if_bol_bo_property_access,
        lr_entity  TYPE REF TO cl_crm_bol_entity,
        lr_col     TYPE REF TO if_bol_bo_col,
        value      TYPE string.
  lr_entity ?= me->collection_wrapper->get_current( ).
  lr_col = lr_entity->get_related_entities( iv_relation_name = 'Relation_Name' ).
  lr_current = lr_col->get_current( ).
* value =
  LS_MAP-CONTEXT_ATTR = 'EXT.ZZZFLD000011'.
  LS_MAP-F4_ATTR      = 'LGORT'.
  APPEND LS_MAP TO: LT_OUTMAP.
*  LS_MAP-CONTEXT_ATTR = 'EXT.ZZZFLD000011'.
*  LS_MAP-F4_ATTR      = 'LANGU'.
*  APPEND LS_MAP TO LT_INMAP.
  IF SY-SUBRC  = 0.
  ENDIF.
  CREATE OBJECT RV_VALUEHELP_DESCRIPTOR
    TYPE
      CL_BSP_WD_VALUEHELP_F4DESCR
    EXPORTING
      IV_HELP_ID                  = 'ZHELP_ZSAKCDD'
*      IV_HELP_ID_KIND             = IF_BSP_WD_VALUEHELP_F4DESCR=>HELP_ID_KIND_COMP
      IV_HELP_ID_KIND             = IF_BSP_WD_VALUEHELP_F4DESCR=>HELP_ID_KIND_NAME
      IV_INPUT_MAPPING            = LT_INMAP
      IV_OUTPUT_MAPPING           = LT_OUTMAP
      iv_trigger_submit           = abap_true
*      IV_F4TITLE                  = ' '"#    EC NOTEXT
endmethod.
But i don't know the Relation_Name which i can get the vender's information.
Another question : i want to trigger the code 'get_related_entities' when i click the search help,
                               How can i do that ?
Thanks.
Oliver.
