在ALV的輸出結果中，要對它的某一行、某一列或者某一單元格進行選定，我們通常的做法是把鼠標直接點擊那一行或者是列就可以了，如果選擇多行或多列，在選擇的條件按住‘CTRL’鍵就可以了。這是手動選擇的方法，但是在實際情況中，有時候需要用程序來對輸出結果進行選擇。

?

1.?????? 首先我們要取得類CL_SALV_SELECTIONS的實例。

DATA? lr_selectionsTYPE REF TO cl_salv_selections.

lr_selections = gr_table->get_selections( ).

2.??????設置選擇模式。

lr_selections->set_selection_mode(if_salv_c_selection_mode=>row_column ).

3.?????? 選擇行

DATA lt_row? TYPE salv_t_row.

APPEND 3 TO lt_row.

??? APPEND 4 TO lt_row.

lr_selections->set_selected_rows( lt_row ).

4.?????? 選擇列

DATA? lt_column TYPEsalv_t_column.

APPEND 3 TO lt_row.

??? APPEND 4 TO lt_row.

lr_selections->set_selected_rows( lt_row ).

5.?????? 選擇一個單元格

DATA? ls_cell TYPEsalv_s_cell.

ls_cell-row = 7.

??? ls_cell-columnname = 'CITYFROM'.

lr_selections->set_current_cell( ls_cell )

6.?????? 選擇多個單元格

DATA ?lt_cell? TYPE salv_t_cell,

???????? ls_cell? TYPE salv_s_cell.

ls_cell-row = 5.

??? ls_cell-columnname = 'CITYFROM'.

??? APPEND ls_cell TO lt_cell.

??? ls_cell-row = 6.

???ls_cell-columnname = 'CITYFROM'.

?? APPEND ls_cellTO lt_cell.

???lr_selections->set_selected_cells( lt_cell ).
