今天学习一个小功能，创建屏幕按钮，明明记得之前学习过，可是很快就忘了，很失望自己的记忆力
哎，笨鸟多分吧，加油，甜柚子
关于添加屏幕按钮
三部：
1
types-pools icon.
tables sscrfields .
data functxt type smp_dyntxt.“如果不要图片可以不要这个
2
selection-screen: function key 1.
function key 2.
3
initialization.
sscrfields-functxt_01 = '模板下载'. "不要图片的按钮
functxt-icon_id = icon_ws_plane.
functxt-icon_text = '飞机模板下载'. 要图片的按钮
sscrfields-functxt_02 = functxt.
at selection-screen.
case sscrfields-ucomm.
when 'FC01'
WHEN 'FC02'
详细代码如下
TYPE-POOLS icon.
TABLES sscrfields.
DATA functxt TYPE smp_dyntxt.
PARAMETERS: p_carrid TYPE s_carr_id,
p_cityfr TYPE s_from_cit.
SELECTION-SCREEN: FUNCTION KEY 1,
FUNCTION KEY 2.
INITIALIZATION.
functxt-icon_id = icon_ws_plane.
functxt-icon_text = '飞机模板下载'.
sscrfields-functxt_01 = functxt.
"functxt-icon_text = 'UA'.
sscrfields-functxt_02 = '模板下载'.
AT SELECTION-SCREEN.
CASE sscrfields-ucomm.
WHEN 'FC01'.
p_carrid = 'LH'.
p_cityfr = 'Frankfurt'.
WHEN 'FC02'.
p_carrid = 'UA'.
p_cityfr = 'Chicago'.
WHEN OTHERS.
...
ENDCASE.
