Accounts and Posting Keys for Company Code Clearing
Description
When maintaining the accounts and the posting keys for clearing between company codes, you can now also specify customer and vendor accounts with the corresponding posting keys instead of G/L accounts.
Exception: If the company code in which posting is carried out is an external company code, G/L accounts must be specified as clearing accounts.
Change system parameters in customizing
The maintenance of accounts and posting keys for company code clearing is
carried out in the General Ledger Accounting Implementation Guide via the 
"Prepare cross-company code transactions" step.
