本文将详细介绍SAP ABAP4中的并行处理技术,包括其概念、优势、实现方法以及实际应用案例。 并行处理的概念 并行处理(Parallel Processing)是指同时执行多个任务或操作,以提高整体处理速度的一种技术。在SAP ABAP中,并行处理主要通过远程函数调用(RFC)的异步调用实现,使得程序能够多线程执行,从而提高处理效率。 并行处理的...

通过下面这段代码模拟一个费时的ABAP程序: 定义一个ABAP函数: 这个函数里执行一大堆计算,然后把传入的product ID写到一张自定义表ZJERRY1里。 调用这个函数的代码: 注意第二种方案使用STARTING NEW TASK达到的并发执行效果: 通过比较,第二种解决方案的效率是第一种的四倍。
By definition, there is no guarantee that data will be processed in a particular order in parallel processing or that a particular result will be available at a given point in processing.· ABAP requirements:¡ The function module that you call must be marked as externally callable. This ...
