我们查看 ABAP 系统根据 Lock Object 自动生成的 Enqueue Function Module,可以发现它有一个名叫 _wait 的输入参数,默认值为 space: 该参数决定了发生锁冲突时的锁行为。 开发人员有以下选择: 初始值: 如果由于存在竞争锁而导致锁定尝试失败,则会触发异常 FOREIGN_LOCK。 X: 如果由于存在竞争锁而导致锁定尝试失败...

abapwait语法 abapwait语法 ABAP开发中处理异步操作需要谨慎设计等待逻辑，避免程序长时间阻塞影响系统性能。WAIT语句主要用于协调不同进程间的数据同步，合理运用能提升程序健壮性。这里用实际开发案例说明WAIT的典型应用场景和注意事项。当需要等待后台任务完成时，WAITUNTIL配合异步函数使用效果显著。比如调用函数BP_JOBSTAT_...

wait 还是不wait,这是个问题。 这是同步更新还是异步更新的问题;如果是只commit work,是异步更新,触发注册在当前SAP LUW中所有数据更新动作,数据更新动作由SAP的更新工作进程来执行,当前程序不等待更新动作结束,直接向下执行。 commit work and wait 是同步更新,此语句触发注册在当前SAP LUW所有数据更新动作,当前主程...
