While refilling consumables, you can top-up the quantity of an existing consumable product instead of creating duplicate entries of the same consumable. The refilled quantities are added and tracked as a new batch.
You can refill consumable quantities from the consumable details page. Go to the Consumable Details sub-tab and click Add Quantity.
Alternatively, you can use the Add Quantity on the details page menu bar to add batches from any sub-tab.
The Add Quantity form displayed is similar to the New Consumable form.
