Configuration of two bank account

Hi Team,

My client is paying the salary end of the month, & after success full they post the salary in Finance.

After salary they process the reimbursement i.e. paying the reimbursement (telephone, fuel, etc.) through off cycle.

After successful they post in FI.

Both (salary & reimbursement) transfer in same bank account.

Client wants two different bank account i.e one for salary transfer & another for reimbursement transfer

How to configure two different bank accounts& impact of this change?

Thank you in advance.

Regards,

Rakesh
