Return Reason codes/ Reversal Reason Code

Question

Good Morning SAP Gurus',
I want to configure reason codes when handling return checks (NSF's).  I don't know which node I should or shouldn't use in this case.  I have something called Return Reason Codes and Define Reasons for Reversals. 
I believe the typical method in handling NSF or return checks is FBRA and assign a reason code but I would also like to somehow systemically add a return fee to the customer account. 
I don't recall where or how that was done.
Any insight?
POINTS AWARDED.
Thanks!

Where will you want to put the return reason code ? is it a global code for a return document or detail code ? I mean store in the row detail.
I suggest to create it in the row line. you can use available one or create a UDF. If you want to use it a mandatory, just develop store procedure or set it as mandatory.
Rgds,
