UI基础四：简单的assign block
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 = .
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：
