Accounting options from subledger to General Ledger

Hi Team,

In our current production instance General Ledger Journal Entry Summarization is set as "Summarize by General Ledger period" now we would like to change and send the details level journal entries to GL and we would like to change that to "Summarize by General Ledger date"

Please confirm if this will impact our existing transactions, will this new change be effective and updated in the balance cube as well.

Thanks,

Bantu
