在ALV的輸出結果中，我們可以利用ALV提供的標準功能(過濾,排序,彙總)對輸出結果正行操作。比如說我們對一個結果進行了排序和過濾等的動作，下次再運行這個報表的時候可以選擇一個功能直接運行這些動作。這就需要佈局（Layout）的功能了。
1. 首先我們設置佈局的功能按鈕。
ls_key-report = sy-repid.
lr_layout = gr_table->get_layout( ).
lr_layout->set_key( ls_key ).
lr_layout->set_save_restriction( l_restrict ).
lr_layout->set_default( 'X' ).
IF p_lay IS NOT INITIAL.
lr_layout->set_initial_layout( p_lay ).
ENDIF.
2. 設置前臺選項頁面。
SELECTION-SCREEN BEGIN OF BLOCK blk WITH FRAME.
PARAMETERS: p_lay LIKE disvariant-variant.
SELECTION-SCREEN SKIP.
PARAMETERS: p_save1 RADIOBUTTON GROUP rg DEFAULT 'X',
p_save2 RADIOBUTTON GROUP rg,
p_save3 RADIOBUTTON GROUP rg.
SELECTION-SCREEN END OF BLOCK blk.
3. 設置前臺佈局選項功能搜索幫助
DATA: ls_layout TYPE salv_s_layout_info,
ls_key TYPE salv_s_layout_key,
l_restrict TYPE salv_de_layout_restriction.
l_restrict = get_restrict( ).
ls_key-report = sy-repid.
ls_layout = cl_salv_layout_service=>f4_layouts(
s_key = ls_key
restrict = l_restrict ).
layout = ls_layout-layout.
