Closing Trial Balance with additional Account Types

As a federal agency, our implementation has adopted the USSGL as required in the Treasury Financial Manual.  To make this work correctly, we have added additional Account Types to the system.

These Account types are now causing issues with the Closing Trial Balance, and by association, I would assume the closing process in general.

PeopleBooks states:

"You can add account types for special circumstances but these require additional changes in your system and are not recommended unless you are prepared to make extensive modifications.

For example, if you add account types, you might also need to modify the Closing Trial Balance Report, GLS1003.SQR."
