Unit Of Measure

Units of measure have two purposes.

Firstly, they are used by items that need to be weighed at POS. In this case you should have a unit of measure called 'KG'. Any items that need to be weighed should have their unit of measure set to 'KG'

Secondly, they are used when doing transferring stock from one item to another to determine the change in quantity.

Example

One item has a unit of measure of 700ML and another item has a unit of measure of NIP (30 mls). When the first item is transferred to the second item, the system uses the unit of measure to work out a ratio. If one bottle of the first item was transferred, the system would decrement the stock of the first item by one and increment the stock of the second item by 23 (23 * 30ml=700ml).

A unit of measure consists of a unit of measure code, a standard measure and a quantity. To be able to transfer stock between items, the items units of measure most be compatible, that is have the same standard measure. Consider the following units of measure.

You could transfer stock between any items which had a unit of measure of 700ML, NIP or MLS because these all have the same standard code of MLS. This means the system can work out the ratios between the units. However, you could not transfer stock from a NIP item into an EACH item because they do not have a common standard measure and therefore the system wouldn't be able to calculate a ratio.
