本文主要是介绍alv简单例子，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
注意点:1,定义一个表头结构,类型为SLIS_T_FIELDCAT_ALV
2,需要赋值的参数,col_ps,fieldname seltext_s(列位置,字段名称,字段文本)
REPORT ztest.
TYPE-POOLS: slis.
DATA: gt_fieldcat TYPE slis_t_fieldcat_alv,
gt_outtab LIKE TABLE OF lfa1 WITH HEADER LINE.
INITIALIZATION.
PERFORM fieldcat_init USING gt_fieldcat[].
START-OF-SELECTION.
PERFORM select_data TABLES gt_outtab.
END-OF-SELECTION.
CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
EXPORTING
it_fieldcat = gt_fieldcat[]
TABLES
t_outtab = gt_outtab.
