Change of Fiscal Year Variant from V9 to V3

Dear Team,

As per the recent amendment in Companies Act, all Indian Companies needs to follow Fiscal Year Variant V3 - April to March, we need to change in one of our Client the Fiscal year in Production Client. Below are the details:

Current Fiscal Year: October - September - V9

Required Fiscal Year: April - March - V3

We have to create a Short End Fiscal Year for the 6 months (Oct. - March) and then re-assign the V3 as Fiscal year to the Co. Code. We studied couple of SAP Notes (S Note: 210861/193713/672255) plus the threads in the same line but getting confused about the steps to be followed.

What all steps needs to be done for shifting the Fiscal year variant? What impact does the change in Fiscal Year Variant makes? How the AA, CO, MM & SD module impact makes?

Regards,
