In one of my project the data type of the variable to hold service consumption result is not known in design time so I have to generate the data type dynamically via code, using ABAP RTTC( runtime type creation ). For detail of RTTC and dynamic programming, please refer tosap help. T...
=,而且此时超类的对象引用需要指向一个和赋值目标对象引用相同子类的对象。 6、 对象引用变量的静态类型(StaticType)和动态类型(Dynamic Type) 静态类型指的是对象引用变量在程序语法申明时引用的类,对象引用变量的静态类型是固定的,不能改变。 而动态类型指的是对象引用变量在程序运行时实际引用的类,可以通过赋值操作...

ABAP-Dynamic Document的应用 1 ALV报表输出的抬头部分是HTML格式的文档，看上去挺美观的。经研究发现，他其实是调用的所谓的Dynamic Document。这是SAP系统中定义的一个全局对象，有一个专门用来说明这个东西的帮助文档。其实我们不需要懂那么多，只要了解几个重点，再懂点HTML的语法，就可以做出相应的输出文档。以下是...
