Units of Measure¶
A unit of measure defines how a quantity is expressed, such as UN, CS, or KG. Codes must remain stable, and conversion rules must exist before combining data expressed in different units.
Path in the platform¶

Granularity and key¶
- Granularity: one row per unit.
- Key: a unique, stable
id.
Required fields¶

Conversions relate a source unit, destination unit, and factor. They must preserve physical equivalence and remain material-specific when the conversion depends on the product.
Dependencies¶
- A unit does not depend on another master record to exist.
- A conversion depends on both source and destination units.
Used by¶
- Supply Planning data model;
- default, sales, and transfer units in Materials;
uomIdin Sell-out and Sell-in;- default Supply Planning unit in Global Planning Parameters;
- execution and presentation unit in the Execution Profile;
- quantitative values in the Demand Plan.
- unit prices and unit costs in Prices and COGS.
- production, storage, handling, transfer, and tax values in Production costs and Logistics and location costs.
Checks¶
- do not reuse the same ID for different units;
- avoid cycles or contradictory conversion factors;
- verify that every transactional unit can be converted to the plan unit;
- do not interpret a missing unit as a zero quantity.
