Assigning default General Ledger accounts (BL/DST)
You can assign the default General Ledger accounts to each process level and sales class combination for inventory and non-stock items in Billing. For example, you can use default General Ledger accounts to track the cost of goods sold (COGS) in Billing.
Before you can assign the default General Ledger accounts at this level in the Billing application, you must define sales classes in the Inventory Control application and assign them to items.
See Inventory Control User Guide.
