This is due to at least one asset or accumulated depreciation control account containing a balance in its subaccount 000. A trial balance, filtered to show subaccounts, will display the cause of the problem more clearly.
If the ledger uses an integrated asset register:
Remove the General Ledger Comparative balances and opening balances for sub account 000 of these assets.
Relocate them to its specific asset sub account.
Delete the current year journal entries against these 000 subaccounts.
Re-enter them for subaccount (001-999) specific to the asset.
Balance forward again.
If the ledger does not use an integrated asset register:
Delete the asset groups. If you use this option, it is required to delete existing assets in the asset register first.
Balance forward again.
If the ledger does not and will not use an integrated asset register:
Open the XPA Administration Tool and remove integration of the asset groups.
Important: This process is carried out on all of the ledger's existing asset groups, and cannot be reversed
Balance forward again.
