India gaap reporting (functional currency is not inr)

Hello Team

There is a wholly owned subsidairy ABC Ltd of a US company in INDIA. It basically buys in USD and sells finished goods in USD to parent company. Hence its functionaly currency is USD. It does have few transactions in INR as well.

For Indian Statutory reporting as per INDIA GAAP, have couple of queries:

In the Month/Year end, does ABC Ltd need to report in USD or INR or both?

If it has to report in INR, how does the USD balance sheet items need to reflect. Example, If ABC Ltd has Receivables in USD, since the functional currency is USD, as such ABC Ltd doesnt revaluate. But for INDIA reporting does it need to re-evaluate the corresponding INR amounts with the latest rates USD/INR rates? 

Thanks
