Hi, Jing,
Probably the easiest way to do this would be to NSF the duplicate receipt in BR. This would automatically do all of the appropriate entries in AR and the GL and would also automatically post the NSF fee for you (assuming you'd allowed for this in your BR bank setup).
If, however, you find you've already just reversed the duplicate receipt in BR, you'd want to manually do an Adjustment in AR for the customer which adjusts the Cash document type and creates a credit for the 'AR to BR Clearing' account. Doing the credit will offset the extra debit to the same account created when the double AR receipt was posted in BR.
