Field help (TPYDACBAN) 

This is the Bank/Cash management in which the all the treasury operations will be recorded. This bank/cash, management is linked to a company (potentially to a specific site). Each bank is linked to a general ledger account (see the Bank accounts documentation). The cash also has its own account defined at the level of the general ledger account parameterisation. It is this account that will be ajusted during the account posting of the payment.
