I am working on a Tree ALV Report and facing a problem in creating field catalog.
While debugging, i came to know about the location where the RunTime error is appearing....
types: begin of t_aufk,
around 20 columns..
end of t_aufk.
data: i_aufk type standard table of t_aufk.
call method g_alv_tree->set_table_for_first_display
i_structure_name = 'T_AUFK'
is_hierarchy_header = l_hierarchy_header
it_outtab = i_AUFK. "table must be empty !
The Error appearing is as follows......
"NO Field Catalog is available"....
How to fix this bug...????
Since i am new to OOPs concepts, i am really struggling to come out of this error...
Pelase Help me out friends.....
