I would like to track donations which received and deposited to various bank accounts.  For various reasons, we have maintain several bank accounts for individual fund category i.e. Enodment, Education assistance, Patient Welfare etc. Similarly, funds received from overseas are kept in seperate bank account.  Please guide my how can I configure in RE?

Under configuration you can add different bank accounts to Financial Institutions.  Are you planning on processing credit card transactions through these bank accounts in batch?  If so you will need to get an IATS (International Automated Ticket System) login and password which needs to be added to business rules. You can then create more than one account to process credit card transactions.  For further info, look at the Electronic Transfer Fund RE user guide and Batch user guide which you can download from the BB website.
