Correcting A Bank Deposit In Odoo Due to Over-deposit: 

When calculating the sum of the bank deposit, if you’ve inadvertently added too much money to the deposit the bank teller will typically deposit the amount you’ve calculated unless he/she catches the error and corrects it at the time of the deposit. If the error is not caught and corrected at the time of the deposit, the error must be corrected in Odoo at the time of reconciliation of the transaction.

The total amount deposited will feed into Odoo through the bank sync as well as another transaction which will be for the amount of the overage the bank takes back from the account (debit).

To reconcile both transactions correctly in Odoo the following will need to be done:

First, reconcile the deposit by matching the transaction to the payment(s) which has already been posted to the customer account(s). The amount of the overpayment will be left to reconcile before this transaction can be ‘validated’ and this step should be performed by selecting ‘manual operations’, entering the GL code  620000 (bank fees) and adding a note on the ‘Label’ line describing the issue (i.e. too much money added to the deposit).

Second, reconcile the debit transaction by selecting ‘manual transaction’, code to GL 620000 (bank fees), and add a note on the ‘Label’ line describing the issue (i.e. too much money added to this deposit).
