It looks like there have been some problems with the new BF field on the Collection Entry screen. BF is for Brokerage Fees, not CODs. COD amounts are entered just like before, always in the COD field. The only time there is an entry in the BF field is when you see a Brokerage Fee prompt with the amount to be collected. This prompt only shows when a package coming from outside the country is being delivered with Brokerage Fees due, which is actually pretty rare. So bottom line, no Brokerage Fee prompt-- no brokerage fee (BF) entry.
