篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了UI基础四：简单的assign block相关的知识，希望对你有一定的参考价值。
经常会有需求让在标准的order加个assign block，那就来简单说一下：
1.创建assign block组件ZXXXXXX
2.添加BTORDER节点和GUID属性
3.创建表视图（可配置，根据情况是否按钮），在表的初始化中DO_INIT_CONTEXT或者DO_PREPARE_OUTPUT中根据GUID带出block信息
METHOD do_init_context. DATA:gr_order TYPE REF TO if_bol_bo_property_access, gw_order TYPE crmst_guid_btil, lr_col TYPE REF TO if_bol_bo_col, lr_valuenode TYPE REF TO cl_bsp_wd_value_node, gt_log TYPE TABLE OF zcrm_proce_log, gw_log LIKE LINE OF gt_log, gt_text TYPE TABLE OF zdelay_reason, gw_text LIKE LINE OF gt_text, gw_struct TYPE zcrms0046, lr_line TYPE REF TO zcrms0046. REFRESH:gt_log. CLEAR:gw_log. super->do_init_context( ). gr_order = me->typed_context->btorder->collection_wrapper->get_current( ). IF gr_order IS BOUND. gr_order->get_properties( IMPORTING es_attributes = gw_order ). SELECT * INTO TABLE gt_log FROM zcrm_proce_log WHERE guid = gw_order-crm_guid. SELECT * INTO TABLE gt_text FROM zdelay_reason WHERE spras = sy-langu. SORT gt_text BY estat. ENDIF. * SELECT * INTO TABLE gt_log FROM zcrm_proce_log WHERE guid = gw_order-crm_guid. CREATE OBJECT lr_col TYPE cl_crm_bol_bo_col. LOOP AT gt_log INTO gw_log. MOVE-CORRESPONDING gw_log TO gw_struct. READ TABLE gt_text INTO gw_text WITH KEY estat = gw_log-zzdlyrsn BINARY SEARCH. IF sy-subrc = 0. gw_struct-in_pro_des = gw_text-text. ENDIF. CREATE DATA lr_line. CREATE OBJECT lr_valuenode EXPORTING iv_data_ref = lr_line. lr_valuenode->set_properties( gw_struct ). lr_col->add( lr_valuenode ). ENDLOOP. me->typed_context->proce->collection_wrapper->set_collection( lr_col ). ENDMETHOD.
将组件添加InterfaceView 并把BTorder节点添加。
将组件添加到BT116H_SRVO的ComponentUsage
在BT116H_SRVO的组件控制器的WD_USAGE_INITIALIZE的方法中添加GUID节点的映射：

在OverView Page中将组件视图添加进来，然后在配置中将组件放出，即可显示。
