看了很多人開發alv報表都寫一大堆複雜的東西。其實可以將這些複雜內容寫在一個包裏，程序調用只需要很簡單的代碼結構即可。
report 調用如下：
REPORT ysdr0004.
INCLUDE y_alv_func.-----"包含文件
perform get_data.-------"取數據
perform show_alv.------"顯示alv
form get_data.
.....
endform.
form show_alv.
DATA title TYPE string.
title = LINES( it_show1 ).
CONCATENATE '記錄共計：' title '條.' INTO title.
alv_set_title title.

SORT it_show1 BY prctr region .
alv_clear_data.
alv_add_data 'IT_SHOW1' '' '' 'CHAR' '' '' 'PRCTR' '利潤中心'.

endform.
