本文介绍如何在WebDynpro应用中创建并使用ALV组件。主要内容包括：创建WebDynpro组件、添加ALV组件、创建节点及属性、设置ALV数据、实现方法以及在视图中嵌入ALV等步骤。

1)Create a Web Dynpro Component ZLM_WDA_0009 and add a ALV Component

WDA: <wbr>A <wbr>Simple <wbr>Test <wbr>of <wbr>ALV

2)Create Node and Attribute

3)Add Elements

a view container for alv

4)Implement the methods

Instantiate ALV when initial

5)Set ALV data

Code:

METHOD wddoinit .

"instantiate ALV conponent object
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage .

lo_cmp_usage =   wd_this ->wd_cpuse_alv ( ) .
IF lo_cmp_usage ->has_active_component ( ) IS INITIAL .
lo_cmp_usage ->create_component ( ) .
ENDIF .

"create node
DATA lo_nd_node_spfli TYPE REF TO if_wd_context_node .
DATA lt_node_spfli TYPE wd_this ->elements_node_spfli .

*  navigate from  to  via lead selection
lo_nd_node_spfli = wd_context ->get_child_node ( name = wd_this ->wdctx_node_spfli ) .

"binding node
DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
lo_interfacecontroller =   wd_this ->wd_cpifc_alv ( ) .

lo_interfacecontroller ->set_data (
*      only_if_new_descr =                 " wdy_boolean
r_node_data =   lo_nd_node_spfli " ref to if_wd_context_node
) .

ENDMETHOD .

6)Embed view for ALV

7)Create Application and test
