需求：
针对Business Role " ZJP_SRV 在Inbox对应的结果清单中，增加如下字段，对应逻辑如下：
- 受付日：维修工单中的受付日CREATED_DATE
- お客様名：维修工单中的お客様名SOLDTO_NAME
- 郵便番号： お客様名客户主数据中的邮编.POSTL_COD1
- 住所：お客様名客户主数据中的地域+市区町村+地名/番地 ZADDRES
- 型番：维修工单中的型番ZZZMODENO
- 故障内容：维修工单中的故障内容描述ZGZNR
实现：
给查询结果结构增加字段：通过append struture 加入到结构CRMST_INBOX_RESULTLIST中
SE24创建处理类：ZY_CL_CRM_AUI_ONEORDER
继承父类:CL_CRM_AUI_ONEORDER
实现对应6个字段的取值：

所以方法参数都是：
ATTRIBUTE_PATH Importing Type NAME_KOMP
VALUE Returning Type Ref To DATA
然后需要让INBOX查询调用这个实现类：SPRO->Customer Relationship Management->Interaction Center WebClient->Agent Inbox
->Basic Settings for Item Types->Assign Implementation Classes:将上面创建的实现类分配给ONEORDER
下面需要去SE24创建树的叶子实现类：ZL_ICCMP_IN_INBOXITEMS_CN02
继承父类：CL_ICCMP_IN_INBOXITEMS_CN02(这个是标准的)
新建6个字段的GET 方法：
METHOD GET_POSTING_DATE. DATA: LR_CURRENT TYPE REF TO IF_BOL_BO_PROPERTY_ACCESS, LR_DATA TYPE REF TO DATA. TRY. LR_CURRENT = ME->BO. LR_DATA = LR_CURRENT->GET_PROPERTY( 'CREATE_DATE' ). "#EC NOTEXT CATCH CX_ROOT. ENDTRY. CHECK LR_DATA IS BOUND. TRY. VALUE = IF_BSP_MODEL_UTIL~CONVERT_TO_STRING( DATA_REF = LR_DATA ATTRIBUTE_PATH = ATTRIBUTE_PATH ). CATCH CX_BSP_CONV_ILLEGAL_REF. FIELD-SYMBOLS: <L_DATA> TYPE DATA. ASSIGN LR_DATA->* TO <L_DATA>. CONCATENATE <L_DATA> '-CURR/QUANT CONV FAILED-' INTO VALUE SEPARATED BY SPACE. "#EC NOTEXT CATCH CX_ROOT. ENDTRY. ENDMETHOD.
所以方法除字段外，其他都一致即可(数量和金额字段另处理)
下面就需要去组件中增加对应字段并放出：BSP_WD_CMPWB - 用户界面组件工作台
ICCMP_INBOX -> ICCMP_INBOX/InboxItems 因为我们只使用tree的，所以只处理这个视图
重定义GET_TABLE_LINE_SAMPLE方法，这个方法是构建树的结构字段的
METHOD get_table_line_sample. TYPES: BEGIN OF line, node_name TYPE string, guid TYPE crmt_genil_object_guid, objectid TYPE crmt_aui_object_id, itemtype TYPE crmt_aui_maincat, description TYPE crmt_aui_description, priority TYPE crmt_aui_priority, status TYPE crmt_aui_status, dueon TYPE crmt_due_date, createdon TYPE crmt_created_at_date, receivedon TYPE crmt_aui_received_on, overdue TYPE crmt_due_date, groupassigned TYPE crmt_aui_group_assigned, employeeassigned TYPE crmt_aui_wi_empl_assigned, customer TYPE crmt_bsp_account, cust_name TYPE crmt_aui_customer, contactperson TYPE crmt_contact, cp_name TYPE crmt_aui_contact_person, datereceived TYPE crmt_created_at_date, timereceived TYPE crmt_aui_changed_at, lastupdate TYPE crm_aui_lastupdate_at, companycode TYPE crm_ic_bd_ccode, logicalsystem TYPE crm_ic_bd_logsys, * back_end_client_descr TYPE crmt_ic_mapped_logsys_descr, " logicalsystem_descr other_employeeassigned TYPE string, other_groupassigned TYPE string, main_cat TYPE crmt_process_type_db, work_priority TYPE crmt_srqm_wp, main_cat_concat TYPE crmt_aui_main_cat_concat, sender TYPE crmt_aui_sender, receiver TYPE crmt_aui_receiver, created_by TYPE crmt_aui_create_by_id, created_by_descr TYPE crmt_aui_create_by_desc, employee_id TYPE crmt_aui_employee_id, employee_concat TYPE crmt_aui_employee_concat, group_id TYPE crmt_aui_group_id, group_concat TYPE crmt_aui_group_concat, customer_concat TYPE crmt_aui_customer_concat, contactperson_concat TYPE crmt_aui_cp_concat, changed_on_at TYPE crmt_aui_changed_on_at, changed_on TYPE crmt_aui_changed_on, changed_at TYPE crmt_aui_changed_at, due_date TYPE crmt_aui_due_date, due_time TYPE crmt_aui_due_time, overdue_icon TYPE string, status_id TYPE crmt_aui_status_id, status_concat TYPE crmt_aui_status_concat, priority_id TYPE crmt_aui_priority, priority_concat TYPE crmt_aui_priority_concat, logicalsystem_descr TYPE crmt_aui_logsys_desc, logicalsystem_concat TYPE crmt_aui_logsys_concat, companycode_desc TYPE crmt_aui_compcode_desc, companycode_concat TYPE crmt_aui_compcodeconcat, categorization_ids TYPE crmt_aui_categorization_ids, categorization_desc TYPE crmt_aui_categorization_desc, checklist_id TYPE crmt_aui_checklist_id, checklist_desc TYPE crmt_aui_checklist_desc, checklist_concat TYPE crmt_aui_checklist_concat, doc_received_on_at TYPE crmt_aui_doc_received_on_at, doc_received_on TYPE crmt_aui_doc_received_on, doc_received_at TYPE crmt_aui_doc_received_at, due_on TYPE crmt_due_date, soc_post_type_des TYPE string, soc_chnl_des TYPE string, soc_senti_des TYPE string, posting_date TYPE crmt_posting_date, zzzmodeno TYPE zmodeno, zsold_name TYPE string, postl_cod1 TYPE ad_pstcd1, zaddres TYPE string, zgznr TYPE string, END OF line. CREATE DATA rv_sample TYPE line. ENDMETHOD.
重定义REFRESH方法：这个方法是指定树的实现方法的
METHOD refresh . DATA: lv_entity TYPE REF TO cl_crm_bol_entity, lv_iterator TYPE REF TO if_bol_bo_col_iterator, lv_root TYPE REF TO if_bsp_wd_tree_node. * super->refresh( ). reset_node_mapper( ). TRY. lv_iterator = me->collection_wrapper->get_iterator( ). lv_entity ?= lv_iterator->get_first( ). WHILE lv_entity IS BOUND. lv_root = me->node_factory->get_proxy( iv_bo = lv_entity iv_proxy_type = 'ZL_ICCMP_IN_INBOXITEMS_CN02' ). lv_root->node_key = add_root_node( lv_root ). lv_entity ?= lv_iterator->get_next( ). ** Changes ITSM CSS Next Gen DATA: lr_cn02 TYPE REF TO cl_iccmp_in_inboxitems_cn02. DATA: lr_owner TYPE REF TO cl_iccmp_in_inboxitems_impl. DATA: lr_context TYPE REF TO cl_iccmp_in_inboxitems_ctxt. lr_context ?= context. CHECK lr_context IS BOUND. lr_owner ?= lr_context->get_owner( ). lr_cn02 ?= lv_root. lr_cn02->set_inbox_switched( lr_owner->compcoinbox->gv_co_inbox_switched ). lr_cn02->set_profile_type( lr_owner->compcoinbox->gv_profile_type ). ** End changes ITSM CSS Next Gen ENDWHILE. CATCH cx_sy_move_cast_error cx_sy_ref_is_initial. ENDTRY. ENDMETHOD.
这时候tree的下级节点的实现类就变成了上面的'ZL_ICCMP_IN_INBOXITEMS_CN02'
到这里基本就已经OK了，去配置页面将字段放出，就可以使用了。
