在ALV显示中加入LOGO
转自：http://www.baidusap.com/abap/alv/4967#2, 例子代码
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：
1, OAER上载Logo
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
输入描述，
上载成功后会有如下提示信息:
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 'ZLOGO'.
完整代码如下：
EPORT ztest_alv_logo.
TYPE-POOLS: slis.

gwa_listheader-typ = 'H'.

APPEND gwa_listheader TO git_listheader.
CLEAR gwa_listheader.
* Type S is used to display key and value pairs
gwa_listheader-typ = 'S'.
gwa_listheader-key = 'Date :' .
CONCATENATE sy-datum+6(2)
sy-datum+4(2)
sy-datum(4)
INTO gwa_listheader-info
SEPARATED BY '/'.
APPEND gwa_listheader TO git_listheader.
CLEAR gwa_listheader.
* Type A is used to display italic font
gwa_listheader-typ = 'A'.
gwa_listheader-key = 'Date :' .
gwa_listheader-info ='SAP ALV Report'.
APPEND gwa_listheader TO git_listheader.
CLEAR gwa_listheader.
ENDFORM. " BUILD_ALV_HEADER
*&---------------------------------------------------------------------*
*& Form top_of_page
*&---------------------------------------------------------------------*
FORM top_of_page.
CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
EXPORTING
it_list_commentary = git_listheader
i_logo = 'ZLOGO'. "LOGO object key 大写
ENDFORM. "top_of_page
3, 运行结果
以上。
