Hi Jaydeep,
There is option 'New Charge/Credit in the Customer Account Monitor.
In this activity you can try selecting 'Customer Charge' and you will be able to select the offsetting G/L accounts which are incomes/expenses related.
So in the journal entry posting it will post to Receivable Account and the Offsetting account is the one which we manually select during the posting of the New Charge/Credit. But you cannot select the bank account directly.
Thanks
