The choice of primary ledger 4 Cs (Currency, Calendar, Chart of Accounts, aCcounting) may seem to be a choice of what the resulting journals and balances look like in your general ledger, but its also influences how transactions are captured in the subledgers.

A few things to consider:

1) Is it legal?

This is a broad spectrum, from strict rules on transaction capture on one or more of the 4Cs which gives you no choice, to legal reporting without restrictions on how your software is configured (only that you produce the report) in which you may choose your corporate 4C’s instead of local.

2) Transactions are captured ONCE

You need to capture ALL the information you need to meet all processing and legal requirements when the transaction enters the system.  Does change of any of the 4Cs affect how this information is captured?  

3) Transactions can be have MULTIPLE accounting representations

With SLA in R12 you can create many accounting representations directly from a single transaction.  (This differs from previous releases where differing accounting representations where only available at the ccid/balances level only) This frees you from 4C restrictions if the purpose is only for accounting.
