Units of Measure

📄️List Units of Measure

List every unit of measure, ordered by type then code. Includes both system-defined units (is_system=true, read-only) and custom units.

📄️Create Unit of Measure

Create a custom unit of measure.

📄️Get Unit of Measure

Get a single unit of measure by id.

📄️Update Unit of Measure

Update a custom unit of measure. All fields are optional - only submitted fields change.

📄️Delete Unit of Measure

Delete a custom unit of measure. System units cannot be deleted, and units still referenced by product configurations, BOM lines, or manufacturing order lines return 422 with the reference count.

📄️List Product Units of Measure

List the unit-of-measure configuration for a product: which unit is the stock unit, which are used for purchasing and sales, and the conversion factor of each unit into stock units.

📄️Update Product Units of Measure

Replace the product's full unit-of-measure configuration in one call. Exactly one row must be the stock unit with conversion_factor 1; at most one purchase unit and at most one sales unit are allowed.

📄️Enable Product Unit of Measure

Idempotently enable a single unit of measure for a product so a bill-of-materials or manufacturing-order line referencing it can be saved without first configuring the full unit-of-measure set. The unit is added as a pending alternate with no conversion factor (0), which lets draft documents validate; a real conversion factor must still be set before the bill of materials can be activated. Calling this repeatedly for the same unit is safe and returns the existing configuration untouched.
