Enhancement on MB1A after saving

Hi,

I am trying to find an enhancement for MB1A after saving it. Out of the many BADI's i assume MB_DOCUMENT_BADI would be the most suitable one, but seems like I have use enhancement spots to add my code. I tried to use debugging point at the USER EXIT MB_CF001 but it did not trigger.

I would like to know if adding the custom code by creating enhancement spot at MB_DOCUMENT_BADI is the best possible method to create enhancement or is there any other better approach for enhancement on MB1A after SAVE?

Thanks,
