ALV Layout problem
I have an ALV report, like the following. (It's just some part of the code, not the whole one).
When I want to print out the ALV it gives me a GETWA_NOT_ASSIGNED shortdump and says the there are unassigned fieldsymbols. Now I know if I'm not modifying the gs_layout it won't give me a shortdump during printing. Could anybody tell me why this problem occured, and how can I handle it?
DATA : gs_layout TYPE slis_layout_alv.
FORM fill_layout .
gs_layout-coltab_fieldname = 'FARB'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
i_callback_program = sy-repid
it_fieldcat = it_fieldcat
is_layout = gs_layout
t_outtab = gt_list
program_error = 1.
ENDFORM. " PRINT_REPORT
