Run the script setup_trial_balance_create.qw_script from the blue title bar of the report /REPORT/TB (right mouse click > Tools > Script Evaluate).
Once the script is complete a new window select option will be created called Trail Balance.
The Trial Balance Art wants is the equivalent of the TRBAL procedure in NV1 which printed a trail balance for users did not have a General Ledger/Trial Balance Report in their books.
