A unit of measure (UOM) conversion lets you buy in the supplier’s unit while stocking and consuming in your floor’s unit. For how the conversion flows across purchasing, receiving, and inventory, see the Purchasing overview. Three units commonly coexist on a purchase:
UnitWhat it’s for
Stock UOMHow the part is tracked in inventory and consumed on a BOM, such as feet.
Purchase UOMHow the supplier sells it, such as roll.
Cost UOMThe unit the unit cost is expressed in, such as per roll.

​
Configure a conversion

A conversion lives on the supplier part number; the link between an ION part and a specific supplier’s SKU. The same part can come from two suppliers in two pack quantities, so each conversion is stored independently.
  1. In ION, open the part in the Parts Library.
  2. Open the Suppliers section on the part.
  3. Click Add Supplier Part to open the Create Supplier Part dialog, then provide:
    • Supplier: pick from your supplier list.
    • Supplier Part Number: the supplier’s SKU.
    • Supplier Part Units: the unit the supplier ships in.
    • Unit of Measure Conversion Factor: how many stock-UOM units are in one supplier-UOM unit.
  4. Save.
To manage the list of available units, see Manage units of measure.

​
On a purchase order

  1. Add the ION part to a PO line. ION offers a Supplier Part picker, populated from that part’s supplier part numbers for the PO’s supplier.
  2. Pick the supplier part. The line switches into the supplier UOM.
  3. Enter the quantity in the supplier UOM.
  4. Enter the unit cost in the supplier UOM.
If you don’t pick a supplier part, the line falls back to the stock UOM. The On Order inventory ION creates is recorded in the stock UOM (500 feet, On Order) even though the line shows 5 rolls.

​
On receiving

  1. The receiver opens the receipt for the PO. The receipt line shows the supplier UOM.
  2. As each unit is received, ION applies the conversion.
  3. The resulting inventory carries the stock UOM.

​
Changing a conversion

When a supplier changes pack quantity, for example from 100-foot rolls to 250-foot rolls, create a new supplier part number with the new conversion factor rather than editing the old one. Old POs reference the old supplier part number and need its conversion to reconcile correctly. ION does not re-apply a changed conversion to receipts already received.
