Add Structure in TYPES declaration When we had to include some structures (Eg VBAP, VBAK) we used to declare a table with header line and include as below But when you need to do similar thing with TYPES we get compilation error (Occasionally not always ) Error: To Resolve this error ...
If we want to reuse the same set of statements more than once in a program, we need to include them in a macro. For example, a macro can be useful for long calculations or for writing complex WRITE statements. We can only use a macro within a program in which it is defined. Macro...

From an object-oriented perspective, polymorphism works in conjunction with inheritance to make it possible for various types within an inheritance tree to be used interchangeably. That is, polymorphism occurs when there is a hierarchy of classes and they are related by inheritance. ABAP polymorphism...
Type I 程式稱為 includes, 目的在減少程式碼, 可以在另一支 ABAP program 使用 INCLUDE 指 令將Type I 的程式包含進來, 通常使用在資料宣告及程式區塊 ABAP Statement 附註說明(ments): 在每列程式的第一個位置標明 * 或在同一列的任一位置以 " 標示. 程式每 列第一個字必須是 ABAP 指令, 如 WRITE ‘...
A nested structure is flat or character-like, depending on the attributes of all of the components.Deep structures contain at least one deep component, at any nesting level. Possible deep components include strings, internal tables, boxed components, data references, or object references....
8. Table Types 9. Structure 28. What are the various types of parameters and how are they distinguished from one another? There are mainly two types of parameters - 1.Formal parameters -This is basically defined when the subroutine gets defined alongside the FORM statement. ...
The purpose of this interface is to declare a method, evaluate, that takes a value and returns a boolean result. Its usage lies in ensuring that all classes implementing this interface adhere to a consistent contract. In this context, I use the interface to implement a higher-order function ...
