Set procurement length and unit for profiles and long-length hardware
Set the procurement length and procurement unit on a SKU so the software knows what per set or per length means for that item.
To set the unit a profile or long-length hardware is measured in, open the SKU's Edit SKU Properties form, expand Additional Properties, add the 'procurement length' and 'procurement unit' properties, choose the unit (Metre or Millimetre) and save with Update.
The procurement unit is set as an additional property on the SKU (for example 'procurement unit' with a value such as Metre or Millimetre); the platform does not itself impose a 3-metre default, so the length used for a profile is the value entered there.
For a profile handle that is not an owned catalogue item, clone the hardware group first to get an editable copy, then open Edit SKU Properties > Additional Properties and set the procurement length and procurement unit (metre or millimetre) before entering the price for that defined length and unit.
For hardware priced per length, such as a gola profile, define the length value (for example 10 ft) and set the procurement unit on the SKU, so the software knows what 'per set' or 'per length' means for that item.
A profile's procurement set size and procurement unit (for example set size 3, unit Metre) make the system round the required quantity up to that multiple, so the purchase quantity reflects what must be bought from the market rather than the exact cut length.
