Unit name display in purchase invoice line item

We have inventory items with different unit names, such as nos, Kg, Liters

When we create purchase invoice and select the inventory item, there is no way to display the unit name associated with inventory item.

Is it supported or we have to create a custom field as list and enter all the unit name again.


If you have multiple unit names represented on an invoice, they will show automatically under the Qty column:


If all unit names are the same, the column heading will be changed:


The unit names do not show on the entry screen, only the finished transaction form. Custom fields are not necessary.
