The secondary unit of measure (UOM) is an additional unit used to quantify goods or services, complementing the primary unit of measure. The primary UOM is typically the main unit used for inventory, purchasing, and sales transactions, while the secondary UOM provides an alternative way to handle and track the same goods in a different format or measurement scale.
To implement secondary UOMs, ERP systems use conversion factors to link the primary and secondary UOMs. For example, if 1 box = 10 pieces
1. Set Base Unit as Kilograms (KG)
- In your Item, Master Data, set the Base UOM (main unit of measure) to Kilograms (KG). This will be the standard unit used in your system for inventory and purchases.
2. Add Other Units of Measure (UOM)
- Go to the UOM section in the system and add other units like grams (G) or milligrams (MG), depending on what units you'll use in invoices.
- Example: You might add G (grams) or MG (milligrams) if you sell items in smaller quantities.
3. Set Conversion Factors
- Set the conversion between units:
- 1 kilogram (kg) = 1000 grams (g) (so, 1 KG is 1000 G).
- 1 gram (g) = 0.001 kilograms (kg) (so, 1 G is 0.001 KG).
- This means when you use grams or milligrams, the system will know how to convert them into kilograms.
