To set up the chart of accounts:
Go to General and General Ledger A/C Maintenance.
Click Add, Key in the Account Number and related details, and save.
Ensure that the debtor and creditor are in the same range setup in the UBS Accounting Module.
This is because the debtor listing will be used as a customer and supplier in the UBS Billing Module.
