CRM WebUI Get related entities and Parent entities

If you need to get entities related (child entities), use GET_RELATED_ENTITY, GET_RELATED_ENTITIES methods

Using GET_RELATED_ENTITY:

    lr_erpadminh ?=   me->typed_context->erpadminh->collection_wrapper->get_current( ).
    CHECK  lr_erpadminh IS BOUND.
    lr_erpadminh->get_property_as_value(  EXPORTING   iv_attr_name =   'VBELN'
                                          IMPORTING   ev_result    =   lv_vbeln ) .

*    CHECK  lv_vbeln IS NOT INITIAL.
    TRY.
        CALL METHOD lr_erpadminh->get_related_entity
          EXPORTING
            iv_relation_name = 'ERPHeaderCondSet'
*           iv_mode          = normal
          RECEIVING
            rv_result        = lr_erpcondh.
      CATCH cx_crm_genil_model_error .
    ENDTRY.
    IF lr_erpcondh IS BOUND.
      TRY.
          CALL METHOD lr_erpcondh->get_related_entities
            EXPORTING
              iv_relation_name = 'ERPCondHAll'
*             iv_child_name    =
*             iv_mode          = NORMAL
*             iv_owned_only    = ABAP_FALSE
            RECEIVING
              rv_result        = lr_condcol.
        CATCH cx_crm_genil_model_error .
      ENDTRY.


      CLEAR  : lr_iterator , ls_condtype.
      lr_iterator   = lr_condcol->get_iterator( ).

If you need parent entities, then use GET_PARENT method

Using GET_PARENT method:

    if iterator is bound.
      current = iterator->get_current( ).
    else.
      current = collection_wrapper->get_current( ).
    endif.

    lr_current ?= current.

    TRY.
      lr_bt_statush ?= lr_current->get_parent( ).

      CATCH cx_crm_genil_model_error .
    ENDTRY.

    TRY.
      lr_bt_adminh ?= lr_bt_statush->get_parent( ).

      CATCH cx_crm_genil_model_error .
    ENDTRY.

    TRY.

    lr_bt_adminh->get_property_as_value(  EXPORTING IV_ATTR_NAME = 'PROCESS_TYPE'
                                            IMPORTING EV_RESULT = lv_process  ).

      CATCH cx_root.
    ENDTRY.
