Dear Venkat,
as explained before, the last date in the deal (end of term) will always be considered exclusively for a fixed term deposit (51a) - so the last interest period will never include this date. Just take the next day as the end of term: the next day excluded will mean the day before included (e.g. 01.01.2013 exclusive -> 31.12.2012 included as last day in calculation).
For 55a deals, the same is valid: except that you can here decide if the first day is included OR the last day (setting 'Inclusive' , field SINCLE, in the structure tab).
We do not allow for the possibility to set both dates to 'inclusive' -
just imagine a roll-over: which of the days is included in which
interest period in this case?
The interest calculation method is not relevant here (exept that the number of days might vary) - and there is no setting or config to change this standard behaviour.
Best regards,
Marie
