Hi Aziz,
I had a requirement of changing Fiscal year variant from Julian to 445 calendar, it was such a high critical change. we did all sort of testing with integrate modules such as MM, SD and PP. Also we have raised a SAP Note.
your requirement is different from mine, however will try to give you some inputs on this.
3 major areas you need to concentrate more, they are Asset Depreciation, Revenue recognition and Controlling planning values.
for asset depreciation we come to a solution to post manual journal entry to adjust Depreciation and for rev req used some utility program to overcome this, we do not have any planned values in Controlling so we are safe in there.
For your requirement you need to create a shortened Fiscal year variant for China calendar and assign Asian Fiscal year variant (April-March) to all other different Fiscal year variants. (T codes: OB29)
Assign same Fiscal variant for Different Controlling areas ( here i have a question are you going to use single Controlling area or different controlling areas)
assign Asset fiscal year variant and execute update the period end dates.
forgot to add a fiscal year variant configuration link.How to set Shortened Fiscal Year Variant
I hope this will help you for further to analyse.
