1. 前言
- 事务代码
- SLG0：创建日志对象、日志子对象
- SLG1：显示应用日志
- SLG3：删除应用日志
- 透明表
- 抬头：BALHDR 应用程序日志: 日志标题
- 行项目：BALDAT 应用程序日志: 日志数据
- 函数模块
- BAL_LOG_CREATE 创建日志处理头
- BAL_LOG_MSG_ADD 向日志处理头中添加消息
- BAL_DB_SAVE 保存日志到数据库
- BAL_DSP_LOG_DISPLAY 显示内存中的消息
2. 创建日志对象
- 事务代码：SLG0
- 创建应用日志对象
- 创建应用日志子对象
3. ABAP中写入SLG1日志
- 代码：
