Interest calculation on FD in SAP

Hi All,

My client has FDs in some banks. They want to make accounting entries related to those FDs in SAP as they normally do in their old system.

My requirement is how to calculate interest on those FDs and make accounting entries of those in SAP FI. We did not use any FSCM module here.

Please guide. I have goggled before posting.

Regards
