Field help (PYHBAN) 

The entry transaction used will determine if cash operations apply to bank or cash funds. The entry transaction also defines if it is mandatory or optional.

Each bank or cash fund is linked to a general ledger account (see the Bank accounts documentation).

The cash account to be posted is determined with respect to this field: each bank includes a set of journals (bank, notes payable/receivable, intermediary posting, etc.), which is used to locate the cash account to be used according to the posting phase. Each cash fund includes a journal and an account used to generate the associated entry.
