SAP JVA Addictional Ledger 4C

Hello,

I would like some suggestions regarding the activation of the JV Ledger 4C JVA Additional Standard Ledger

4A and 4B ledger are alredy activated.

Regarding the 4C JV Ledger I have some questions:

1. Posting actual transactions (for example a FI Invoice or a GL voucher) will imply to book on 4A and 4C ledger?
2. Is it possible to book only on 4C JV Ledger? If yes how?
3. How to decide in which JV ledger (4A or 4C) to record the transactions?

Suggestions and answers are appreciated

Thanks

Kind regards,

Francesco
