2.1ABAP程序类型

1. Executable program,可执行程序,使用SUBMIT,dynpro,使用Tcode执行selection screen,不能再Function Module中使用;

2. Class pool,类,使用Call,只能在Method中使用;

3. Function group or function pool,使用CALL FUNCTION执行;

4. Interface pool,接口;

5. Module pool,使用Tcode执行的dynpro;

6. Subroutine pool,子程序;

7. Type group or type pool,数据类型;

   

程序类型声明

1. REPORT;
