The "Do not allow manual entry" should be added as an option to the Legal entity overrides.

We have many clients that have global operations where certain subsidiaries record their financial results as a ledger entry (monthly trial balance results) instead of having full operations transacted in each subledger.

They would often like to use a Shared Chart of accounts for all of these subsidiaries. However, the "Do not allow manual entry" flag on a Main account prevents that usage. If that is set on an account (such as Accounts receivable), that account is appropriately configured if all activity goes through the AR subledger. However, that account would then be prevented from being used in other Legal entities where they record ledger entries for their financial results.

Therefore, the Legal entity override should allow setting that differently than the global setting.
