Editing Common control account

Hi,

We created a primary ledger in Oracle Fusion with the Common Control Account (CCA) option enabled. Now we need to change this setting, as our business requires different intercompany accounts for each company rather than a common control account. We understand from Oracle documentation that certain fundamental ledger attributes (such as COA, calendar, and currency) are permanently fixed once the ledger is created. Could you please confirm if the CCA setting also falls under this restriction, and if there is any other way to edit or disable CCA after ledger creation? If not, kindly advise the recommended Oracle best practice
