Hi, Anuradha!

I have a strong suspicion that dump actually happens in q_gv_alv->set_ready_for_input.

Please have a thorough look at your table q_itab and fieldcatalog q_gv_fieldcatalog structures (or share them). Probably something's wrong with fieldcatalog. Do you fill it manually? Or it is filled basing upon some structure?

You can make a quick debug of both methods (set_ready_for_input and register_edit_event) to be sure about the place of dump. I guess after that you'll find out the reasons of it.

Hi,

There is a problem with your field catalog.

Check it if the fieldnames that are provided are correct

and

In the event handler method, check if the field name used is correct.

Dump information will be pointing to the part of code which is responsible for this error.

Can you share the screenshot of that.
