Hi,

I am new to the abap objects and till now i am to understand that the role of the global classes are important in the abap object program. I had tried to search on the net but i was not able to get the desired result.

I want to know which are the major global classes which are used in the ABAP objects.

Plzz provide me guidelines for it.

Hi ricx,

There are lot of global classes available.

You can search in SE24. For every functional, there are hundreds of classes which are used for a specific purpose.

For alv, CL_GUI_ALV_GRID we use this class.

Regards,

Arun.

Hi Ric,

a global class is simply a class that has been defined so that it is available "globally" - i.e. it can be instantiated and/or called from other processes.

The alternative is a local class that is defined inside an ABAP executable program and is only visible to that program.

Cheers

Graham Robbo

p.s. If you still want to look at a global class use transaction SE24.

So search for global classes that have "GUI" in their name.

Jeez dude - get on with it!
