You can fix this by recalculating the balances in 1-6 Period/Fiscal Year Management.

1. Log all users out of the Sage 100 Contractor company.
2. Open the company with Administrator rights and exclusive access.
3. Open 1-6 Period/Fiscal Year Management and click Recalculate Balances.
4. Click the Recalculate Balances button and try it again.
5. If the error persists, click the Recalculate Balances button again and try it again.

If the errors persist, you will need a file fix. Log a support ticket through the customer portal, and a support specialist will follow up with you.

 NOTE: Before contacting Sage support, ensure you have the Administrator rights and exclusive access to the company and have access to the server for backup purposes
