如果需要使用代码实现下面的search 功能:

我们可以使用如下代码，通过重用BOL 层的query来实现搜索。

DATA: lo_core                TYPE REF TO cl_crm_bol_core,lo_collection          TYPE REF TO if_bol_entity_col,lv_query_name          TYPE crmt_ext_obj_name,lt_selection_parameter TYPE genilt_selection_parameter_tab,ls_selection_parameter TYPE genilt_selection_parameter,ls_query_parameters    TYPE genilt_query_parameters.ls_selection_parameter-attr_name = 'MAINCATEGORY'.
ls_selection_parameter-option =  'EQ'.
ls_selection_parameter-sign = 'I'.
ls_selection_parameter-low =  'SRVO'.
APPEND ls_selection_parameter TO lt_selection_parameter.ls_selection_parameter-attr_name = 'POSTING_DATE'.
ls_selection_parameter-option =  'BT'.
ls_selection_parameter-sign = 'I'.
ls_selection_parameter-low =  '20140318'.
ls_selection_parameter-high = '20140320'.
APPEND ls_selection_parameter TO lt_selection_parameter.ls_query_parameters-max_hits = 1.
lv_query_name = 'BTAdvQueryAUI'.lo_core = cl_crm_bol_core=>get_instance( ).
lo_core->load_component_set( 'BT' ).lo_collection = lo_core->dquery(iv_query_name               = lv_query_nameit_selection_parameters     = lt_selection_parameteris_query_parameters         = ls_query_parameters ).当然我们也可以更深入一层，重用Genil layer的实现代码来执行搜索:代码如下:DATA: lo_tool TYPE REF TO zcl_crm_queryaui_run_btil.DATA: lt_parameter TYPE crmt_name_value_pair_tab,ls_parameter LIKE LINE OF lt_parameter,lt_sel_para  TYPE genilt_selection_parameter_tab,ls_sel_para  LIKE LINE OF lt_sel_para.ls_parameter-name = 'MAINCATEGORY'.
ls_parameter-value = 'SRVO'.
APPEND ls_parameter TO lt_parameter.ls_parameter-name = 'POSTING_DATE'.
ls_parameter-value = '20140318'.
APPEND ls_parameter TO lt_parameter.ls_sel_para-attr_name = 'MAINCATEGORY'.
ls_sel_para-sign = 'I'.
ls_sel_para-option = 'EQ'.
ls_sel_para-low = 'SRVO'.
APPEND ls_sel_para TO lt_sel_para.ls_sel_para-attr_name = 'POSTING_DATE'.
ls_sel_para-sign = 'I'.
ls_sel_para-option = 'BT'.
ls_sel_para-low = '20140318'.
ls_sel_para-high = '20140320'.
APPEND ls_sel_para TO lt_sel_para.CREATE OBJECT lo_tool EXPORTING iv_objname = 'BTAdvQueryAUI'.lo_tool->read( i_param_tab             = lt_parameterit_selection_parameters = lt_sel_paraiv_advanced_search      = abap_true ).DATA(result) = lo_tool->get( ).

这里的zcl_crm_queryaui_run_btil是一个新的class，继承自cl_crm_queryaui_run_btil。继承的原因是我们需要使用GET_RESULT_LIST和READ_BUSINESS_TRANSACTIONS这两个protected方法。sub class的代码如下:
