1.如何在SMARTFORM中打印图片
在使用SmartForms进行打印单据开发时候，经常需要将公司的LOGO、公司印章、管理人员签名等一并打印，而这些打印对象都是图片，需要将这些打印对象上传到SAP服务器中，才能在SmartForms中应用。如何上传和应用这类图片，下面是具体操作步骤介绍：
1 .执行SE78事务码，按如下图操作。

上传的图片一定要是BMP或DIB格式，选择上传图片的路径，填写名字和描述，然后一直执行下去就可以了，执行成功后显示如下。

2. 在SmartForms设计时，在想要加入LOGO的地方，点击右键：创建->图形，然后在名称：ZERPLOGO，即可才打印的Form中打印出公司的LOGO或其它图形、图片。

2.如何在ALV报表中显示图片
具体操作步骤：
1 . 执行OAER事务码，按如下图操作。

Class name：PICTURES
Class type : OT
Object key：ZALV_LOGO (ALV报表程序通过这识别）
2. 填写完成点击执行按钮（或F8）运行之后，打开标准文档类型->双击屏幕，上传本地图片文件至SAP（如下图）

然后一直执行下去就可以了，执行成功后显示如下。

3 . 上传完成后，可以在ALV报表中使用了，可以使用如下function使用图片

  CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
    EXPORTING
      it_list_commentary = git_listheader
      i_logo  = 'ZALV_LOGO'.  " 要大写

3 . 如何下载SE78上传的图片到本地

在使用Scripfrom或SmartForms工具开发凭证单据打印的时候，经常会遇到需要打印一些相关的图片到单据上的需求，比如：公司的LOGO，公司的印章、领导签名图片等。

在SAP系统单据打印开发中，我们还可能会遇到这样需求，比如:某些己开发的打印单据需要更换公司LOGO、领导签名图片等，我们可能需要下载原来图片进行修改，参考设计等

但SAP好像并没有标准的事务码可以方便下载已上传至SAP服务器上的图片，通常的解决方法写一个专门下载这类图片的简单程序来处理。

比如下面这个程序是网络上被转载较广的专门用于下载SE78上传图片的程序，操作界面如下：

输入图片名称和下载到电脑的本地路径，点击执行即可完成所需图片的下载。

源代码如下仅供参考：
