Operation that cancels any database changes made since the beginning of an LUW (Logical Unit of Work) - that is, since the last database commit - when an error occurs in that LUW. In the R/3 System, a database rollback is triggered automatically, or by the ABAP keyword ROLLBACK WORK, or by the appropriate Native SQL command for the database system.

当在一个 LUW（Logic Unit of Work）中发生错误时，可以撤销从它开始以后做的任何数据库修改，就是说，从上次数据库提交之后。在 R/3 系统中，数据库回滚自动触发，或者通过 ABAP 关键字 ROLLBACK WORK，或者通过数据库系统的相关 Native SQL 命令。
