Hello Ravi,
You should define a non-leading ledger for Indian GAAP. You can maintain the currency and fiscal year for this non-leading ledger.
Define one more depreciation area say 32 for group currency (INR) which will derive the value from area 01.
Then you have to define a virtual depreciation area which will post the difference between 02 and 32. This will only be posted only to non-leading leger.
