Unit names are set in the Inventory Items tab by editing the individual items. See Create and manage inventory items | Manager. Names set there will appear on purchase and sales invoices under the Qty column. Of, if everything on the invoice has the same unit name, that column will be renamed to match.
I don’t know what you mean by “how to calculate the unit name column.”
As for reports, entries are in the unit name defined for any given item, but do not show on the reports.
Thank you for your reply. I need a total of the qty column (the unit name column). Just the amount columns in the general ledger of purchase invoices and sales invoices are calculated. I want to know how many litres of stock I bought and sold. Currently, with a calculator I count the liters on every sales invoice and every purchase invoice. Do you understand?
Is there a report that can give me a total, for a specific period, for the total amount of liters I bought and sold? The Ltr colum is not on the reports
Yes, I have that report. Which report is for the quantity liters sold to customers? The sales invoices by item give a total amount of money, not liters
