Creating the parameter

You can create parameters with the Parameter Type UOM Conversion Factor or Variable UOM to process weight-based rollups.

Creating a parameter with the UOM Conversion Factor parameter type

You can create a parameter with the UOM Conversion Factor parameter type. The UOM Conversion Factor parameter type works with two different UOM types, such as mass and Volume (Density) or mass and count UOMs. You must create a parameter with the UOM Conversion Factor parameter type if you are using a count UOM on material items.

A UOM Conversion Factor parameter type is appropriate when you are doing a basic pack conversion. Item units can default to a count type UOM with the UOM Conversion Factor parameter type.

  1. Create the parameter in the Parameter form.
  2. Specify a description for the parameter.
  3. Select UOM Conversion Factor from the Parameter Type list.
  4. Select a mass UOM (e.g. g, ounce, kg, etc) in the UOM Extend list.
  5. Select a count UOM (e.g. each) in the Per UOM list.
  6. Assign the parameter to the lab as a rollup parameter.
  7. Set up Items. Enter unit weight for each item to be handled as count type.
  8. You can assign a count UOM or mass UOM value for the item and enter the weight value for the UOM Conversion Factor parameter.
  9. Add the item to the Formula > Item Lines tab. Keep the default UOM or specify a count UOM in the UM field.

Creating a parameter with the Variable UOM parameter type

You can create a parameter with the Variable UOM parameter type.

Do not use a Variable UOM parameter type with a count UOM on Items if you will be using the Ingredient Statement module. The Variable UOM parameter cannot be selected as the base unit of measure.

If you must create multiple conversions such as cups sliced and cups shredded, use the Variable UOM parameter type.

  1. Create the parameter in the Parameter form.
  2. Specify a description for the parameter. You must specify a unique description. The description cannot be a duplicate of any UOM description since users will only see descriptions in the droplist.
  3. Select Variable UOM from the Parameter Type list.
  4. Select a mass UOM (e.g. g, ounce, kg, etc) in the UOM Extend list.
  5. Keep the value in the Per UOM list blank. You do not need to select a value.
  6. Assign the parameter to the lab as a rollup parameter.
  7. Set up Items. Assign a mass UOM value for the item and enter the weight values for the Variable UOM parameters.
  8. Add the item to the Formula > Item Lines tab. The Variable UOM parameter does not appear automatically. You must select the Variable UOM parameter UOM for the item.
