Go-live in EC-CS:update trading partner and transaction type on Balances

Hi collegues,

We are on a go-live this december for EC-CS (consolidation) but never have used trading partner nor consolidation transaction type so there are not GL account balances differenciated by these two items on our FMGLFLEXT database for the operative ledger.

Which is the best option for the data to be collected into our consolidation ledger in EC-CS (ECMCT database) when data transfer for all our consolidation units will be realtime update from FI?

I really don't know if I must correct the balance on FMGLFLEXT throught FI postings or if just adjustments on EC-CS it's the best option. I'm thinking on the posibility of extracting the Financial Statement at any time from F.01 tx...

Is there any transaction on FI to authomatically update at least the trading partner on GL accounts positions/balances?

Thanks in advance!

Regards,
