I am new to oops I have created a small program to display data. I have declared a small struture in the Public section. but when I see the internal table in the debugging mode it contains 2 fields as KEYPART FUNCPART instead of fields which are return in the internal table decleration. and the program in going to dump.

the report is as follows

Thanks for your reply,

As with in the display I called Pass_to_alv and with in the Pass_to_alv I have called retrieve_data method as there is no problem there. Please run the report in the debug mode as you cannot see the fields ( kunnr name1 land1 ort01 ) in the table as it shows 2 fields KEYPART FUNCPART. The problem lines there.
