appending nested internal table

[Former Member]

Hi,

How to append data in nested internal table for eg

data : cht_todo type me59_s_todo.

now me59_s_todo is itself a nested structure having a table me59_t_items

me59_t_items is also a nested structure having a table messages.

No I have to append some value in this me59_t_items - message table

ie cht_todo -> items -> messages

cht_Todo contain items

items contain messages

How to append value in this message table.?
