SAP图片相关：

链接: 【SAP ABAP学习资料】屏幕图片预览
链接: 【SAP ABAP学习资料】smartforms打印图片，动态打印图片
需求：
SAP上传图片只能本地电脑选择图片通过SE78或PERFORM IMPORT_BITMAP_BDS上传，现产品有专门的产品库系统管理，产品信息全部在产品库维护，要求用户上传在产品库的图片能同步至SAP，SAP打印合同能带出来图片信息。
解决方案
研究SAP图片上传发现，SAP系统图片保存数据为16进制数据，IMPORT_BITMAP_BDS方法先将本地链接地址的图片信息转成16进制数据，再保存到SAP数据表。
我们可以跳过转换步骤，直接上传16进制数据保存至SAP数据库，这样产品库图片可以直接调用RFC接口上传图片
功能实现
1.重写import_bitmap_bds方法
（包含文件LSTXBITMAPSF05）
可以将import_bitmap_bds复制出来重写，我这里是直接在包含文件下创建了隐式增强

2.创建RFC函数
SAP只支持BMP格式图片上传，而且smartforms图片打印不支持自适应大小，所以需要在接口里面转换上传的图片格式，裁剪图片大小后再上传至SAP

3.调用RFC接口，上传图片
完成上面两步后，产品库只需要将图片转成16进制，调用SAP 发布的RFC接口就可以将图片上传同步至SAP。
