Hi,
You need to create two configuration to achieve the same. Eg you created configuraton ZKEY <DEFAULT> <DEFAULT> <DEFAULT> and ZKEY <DEFAULT> <DEFAULT> <ZTA1>
suppose you want to change configuration based on field in btadminh. Then your code will be as follows:
You need to write this code in do_config_determination.
DATA:
    lv_val         TYPE              char2,
    lv_obj_typ      TYPE              bsp_dlc_object_type       VALUE '<DEFAULT>',
    lv_obj_subtyp   TYPE              BSP_DLC_OBJECT_SUB_TYPE   value '<DEFAULT>',
    lr_node        TYPE REF TO       if_bol_bo_property_access.
  CALL METHOD super->do_config_determination
    EXPORTING
      iv_first_time = abap_false.
  lr_node = typed_context->BTAdminH->collection_wrapper->get_current( ).
  CHECK lr_node IS BOUND.
  lr_node->get_property_as_value(
    EXPORTING
      iv_attr_name = 'Your attribute in BTAdminH'
    IMPORTING
      ev_result    = lv_val ).
  CASE lv_val .
    WHEN 'XYZ'.
      lv_obj_subtyp = 'ZTA1'.
    WHEN 'ABC'.
      lv_obj_subtyp = '<Default>'.
  ENDCASE.
  me->set_config_keys( iv_object_type          = lv_obj_typ
                       iv_object_sub_type      = lv_obj_subtyp
                       iv_propagate_2_children = abap_true ).
ENDMETHOD.
