Russian Legal Fiscal Variant

As our Russian company code has a different fiscal year variant for legal purposes then the other companies and S4HC only allows 1 fiscal year variant for all companies, we would like to understand how SAP envisages to comply with this regulation. Is it required to set-up parallel ledgers for this purpose, or do you use another way to have the SAP standard local statutory reporting (and interfaces to the government) comply with the Russian Fiscal Year variant?
