Security Deposit Partial Release/Interest Calcualtion

Hi Experts,

I'm new to SAP FICA.

I have few quires regarding Security Deposit Partial Release/Interest calculation.

1. When a Security Deposit is partially released, system shows the partial release date with respective to Security Deposit start date.

    Is this the standard behavior, or else is there any other way to check partial release date of Security Deposit.

     Example:

     Security Deposit start date = 01.01.2014

     Security Deposit Partial release date (happens on 16.09.2014) = 01.01.2014 (system populated Security Deposit start date)

2. In the event of partial release of Security Deposit, is there a feasibility to calculate the interest on Security Deposit at this point of time.

    If so, is there a standard configuration or else it should be custom.

Thanks in Advance

Regards
