[代码]如何在ALV头中显示Logo图片-[REUSE_ALV_GRID_DISPLAY]详解编程语言

下面介绍如何在ALV头中显示Logo图片的方法，其中ALV是调用函数REUSE_ALV_GRID_DISPLAY创建的。详细步骤如下：

Tcode： OAER上载需要显示的LOGO图片，

输入Class name  ’PICTURERS ,Class type以及Object key ‘ZLOGO ，这个ZLOGO就是logo的标识，会在ALV程序中用到。

运行后，双击screen上载logo

上载成功后会有如下提示信息:

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 ZLOGO .

完整代码如下：

REPORT ztest_alv_logo.
