abap 本地包 生成请求号
先要将目标对象放到可传输的包中,再包请求,具体步骤如下:
第一步:
T-CODE:SE80,选择本地对象
第二步:
选中你想包请求的对象,点击右键,弹出菜单中选择“其它功能->更改包分配”
第三步:
弹出框中输入你想分配到的包,点击勾按钮或回车
第四步:
弹出窗口中,选择请求号或创建请求
参考技术A se38进入到程序里 goto->object directory entry或者 转到->对象文件目录选中后,在弹出窗口里点修改按钮,然后把package从$tmp改成你们那要求的开发package,确认后就可以选择请求号了。 参考技术B
本地包不能生成传输请求的,下面是传输步骤,需要修改开发包;
SE38打开程序,然后菜单栏中:转到 -> 对象目录条目;
在弹出窗口中单击修改按钮,输入一个已经存在的开发包;
单击保存,就会提示生成请求的界面;
ABAP系列SAP ABAP 实现FTP的文件上传与下载
前言部分

正文部分
在SAP的实际应用中,经常会需要将生成的文件上传到FTP,或从FTP下载相关文档数据。本例实现将本地指定文件上传到FTP,及从FTP下载文件到本地的功能。
从FTP复制文件共有两种方式,一种是直接复制文件,另一种方式是先从FTP读取文件数据到内表,拷贝再写入指定位置文件,不过该功能仅支持文本格式文件(*.TXT,*.DAT),一般不予推荐。
相关函数:
1)FTP_CONNECT:通过账号连接FTP。
2)FTP_COMMAND:执行FTP操作命令(注意,程序中所有命令必须为小写)。
1cd:指定本地文件夹路径;
cd:指定FTP文件夹路径;
put <filename>:上传文件;
get <filename>:下载文件;
3)FTP_SERVER_TO_R3:将FTP上的指定文本文件数据读取到内表。
4)FTP_DISCONNECT:关闭FTP连接。

本人很菜,想知道sap abap开发中为啥有时修改需要请求号
