Hi,

For adding the 'Unit Of Measure' to a product, follow the steps.

1- Enable the 'Unit of Measure' in settings.

2- Assign UOM to the products.

In this way we can set UOM for all the products.

Hope it helps.

The list of units of measurement is on the sales tab - and applies to sales, purchase and manufacturing orders:

In my opinion, this is broken - it makes no sense to allow tons to be used as a UoM when the inventory UoM is Units
