Hi,

Basically there is no difference in using classes and functions.

But classes provide you extra functionalities.

Thanks,

ALV with FM uses standard FMs from reuse classes, while OOPS is more methodical & gives a lot of powerful functions to the existing grid ALV.

incase you are developing a report with normal functionality then you can use FM or Classes.

When do we use Classes for ALV and when FM for ALV.

if the functionality includes some complex things like Drop Downs list box at column level, and Cells editable disable and enable etc..

then we can't do that with FM, so in that case we have to use Classes.

other cases we can go for FM's.

Hi Gajanan,

You can use OOPs concept for ALV when you need to display a Report on a Screen where as ALV through FM are displayed on List Processing.

Moreover you have got some additional Funcationalities like Dragdrop, oyu can create Tree Report and so on using OOPs concept.

Hope you should be clear now.

Thanks,
