Need help on ALV Print dump.

Hi,

I am getting a Print dump when I want to print the Output list of ALV Report. I have given the checkbox for print on the selection screen default ''. An I am also passing 'X' for the Print in the initialization and passing the structure to FM REUSE_ALV_GRID_DISPLAY. And II'm getting dump 'GETWA_NOT_ASSIGNED' ,

The current ABAP/4 program "SAPLKKBL " had to be terminated because

one of the statements could not be executed. Could any of you help one this problem.

Regards,

Mira
