Changing Fiscal Year from Non-calendar FY to Calendar FY in the middle of the Year

Hi Experts,

We have a Company Code with Fiscal Year Variant "V3".

So, as per the current setup, the Financial Year is from April'15 to March'16.

Due the recent corporate decision, the Fiscal Year needs to be changed as Jan - Dec.

So... literally, we need to end the ongoing Fiscal Year by 31.12.2015 and it should be a New Fiscal Year for Jan'16 to Dec'16 & onwards.

I seek the help:

Is there any OSS Note which explains details steps to be executed to bring this change - Converting the ongoing Fiscal Year to Shortened Fiscal Year

OR

Can any body has full details of the process to be followed to achieve this.

Any useful suggestions, content is well appreciated.

Thanks
