Hi
The system is generating default values for virtual columns.
II have created a workaround as follows:

FUNCTION list_rowcols_w_dict_defaults RETURN t_tab_list IS
v_result t_tab_list;
v_list_padding t_vc2_30;
v_index PLS_INTEGER;
v_operator_padding PLS_INTEGER;
BEGIN
v_list_padding := get_list_padding(4);
v_operator_padding := get_operator_padding;
FOR i IN 1 .. g_columns.count
LOOP
IF g_columns(i).data_default IS NOT NULL
AND g_columns(i).is_hidden_yn = 'N'
AND g_columns(i).is_virtual_yn = 'N' ---- ADJUSTMENT LVK
