Deleting duplicate data from a deep structure

Hi Friends,

I have this deep structure in my program (an internal table which contains another internal table).

I fetch data in it and now I want to delete adjacent duplicates from that deep structure.

I have used the command " DELTE ADJACENT DUPLICATES..COMPARING ALL FIELDS".

But it appears this has no effect on the deep structure.

Kindly suggest or let me know if my understanding is wrong.

Regards,

Shoeb
