In AX2012, open balance transactions were created in accordance to current account structure and fixed dimension values setup.

Unfortunately, this very useful option is for some reason no longer available in D365.

The reason, why this option is so useful is, that in case users changed the account structure - add or remove financial dimensions or define new default dimension values on ledger accounts - based on their organizational changes, the old transactions were in most cases automatically adjusted to the new setup with the opening balances.

Currently, users would need to do the manual correction before they make adjustments to accounting structure and fixed dimension values. But they usually do not think of it and if they want to do corrections later, they need to revert the changes in accounting structure and financial dimension values, which is not recommended. Updating subledger accounts to the new setup is even more challenging.

If removing this feature was requested by some clients, it should still be available for others by including it as a feature or as a setup option.
