1, OAER上载Logo
Tcode： OAER上载需要显示的LOGO图片，
输入Class name ’PICTURES',Class type以及Object key ‘ZYINHELOGO'，这个ZYINHELOGO就是logo的标识，会在ALV程序中用到。
运行后，双击屏幕上载logo
输入描述
确定之后会提示上传成功
2, 例子代码
代码逻辑：
1，从SPFLI中抽取数据
2，调用REUSE_ALV_GRID_DISPLAY创建ALV，需要指定 i_callback_top_of_page参数
3，在回调函数top_of_page中，调用 REUSE_ALV_COMMENTARY_WRITE指定显示logo的object ID 'ZYINHELOGO'.
完整代码如下
