difference between using FM and class in alv

does anyone know what's the main difference between using FM to create alv and using class to create alv?

in what condition we usually use FM or class?

The FM allow you to develop plain, ordinary ALV reports quickly and easily. If you want something more complex, you'll need to use classes. By using the classes, you get more flexibility - you can do more with the alv .

Function Module is is a reusable piece of code that is primarily procedural oriented.

Class is also a similar reusable code, but the basic difference here, is that classes are object oriented.

YOu can search the forum with your sibject line and you can get a lot of answers.

YOu can have a look at the sample programs:

demo_function_group_counter

and

demo_class_counter

to notice the difference

using FM we can create Classical and Interactive ALV Reports.

The classes are used to create the ALV Reports with OOPS concept.
