data conversion for Jalali calendar.

Hi experts

We're about to start a project for an Iranian Company.Iran uses Jalali calendar instead of Gregorian calander.ERP uses Gregorian calendar for the records such as registration documents in the database.But we want to build BW System as it can be used in both calendars.So, is there any possible way for converting date fields from Gregorian to Jalali calendar automatically and put that exact date in Jalali in the report, such as 22.01.2015 ?

thanks for any suggestion..
