Leading Ledger 4-4-5 vs. Non Leading -Calendar Months. How to calculate Actual Cost for Non Leading Ledger

Hi Experts,

Currently we are following 4-4-5 calendar in Leading Ledger which is based on US GAAP. Now while implementing for Russia, we need to have Non Leading Ledger based on Calendar Month based Fiscal Year Variant.

Currently we follw Actual Costing through Material Ledger for US Gaap. As Russian Accounting Standard also need Actual Cost Calculation, we need to understand how Actual Rate Calculation is possible for NLL.

We are also aware of the new functionality in EHP6 i.e. FIN_CO_COGM, but as the end date is different in LL and NLL ledger, it looks difficult to get what is required.

Any suggestions on the same. Thanks in Advance.
