Dear Rivera Adriana
The situation is like this!
There are two possibilities to Reverse transaction and flows:
1. Reverse trough FTR_EDIT transaction -> "Reverse" button

Clik here to view.
From here you can reverse Activity. Activity depends on Processing Category (like Order - Contract - Settlement, etc).
If you have Settlement - it is very usefull. Becasue when you do reverse operation you reverse Settlement activity to Contract activity + First flow (or all flows if they were not reversed with the second possibility). When you've go Contract activity - you can still work with transaction - to enter new conditions, etc.
When you don't have Settlement activity, you reverse Contract activity. Before Contract activity there is no any other activity (usually) - so the transaction is fully reversed. You won't be able to work with transaction anymore.
2. Reverse mode at "Cash flow" tab.

Clik here to view.
Here you can reverse flows except the first flow.
