How to Set Up Catch Weights for an Item

Before you can use catch weights, you need to configure items with an alternate unit of measure. This article walks you through the process.

Prerequisites

Set Up an Item for Catch Weights

  1. Open the Item List or Item Card
  2. Find the item you want to configure and open it
  3. On the Item Card, locate the Catch Weights section (near the bottom of the page)
  4. In the Alternate Unit of Measure field, enter the code of the unit of measure you want to use as the catch weight unit (e.g., "KG" for kilogram)
  5. Verify the alternate unit is correct by checking the Item Unit of Measure table to ensure the conversion factor is configured

Configure Item-Level Pricing (Optional)

By default, items use the pricing method defined in Catch Weight Setup. To override this for a specific item:

  1. In the Catch Weight Sales Pricing field, select:

    • Default - Use base unit pricing
    • Alternate Unit of Measure - Use catch weight unit pricing

  2. In the Catch Weight Purchase Pricing field, select:

    • Default - Use base unit pricing
    • Alternate Unit of Measure - Use catch weight unit pricing

Configure Item-Level Tolerance (Optional)

  1. In the Alt. Quantity Tolerance % field, enter the tolerance percentage for this item
  2. This overrides the default tolerance set in Catch Weight Setup

Set Up Unit of Measure Conversion

When you set an alternate unit of measure, you need to ensure the conversion factor is configured:

  1. Select Item Units of Measure from the Item Card
  2. Find or create the alternate unit
  3. In the Qty. per Unit of Measure field, enter the conversion factor
    • Example: If 1 PALLET = 20 BOXES, enter 20
  4. Optionally configure:
    • Catch Weight Rounding - Rounding method for catch weight calculations
    • Catch Weight Rounding Precision - Number of decimal places for rounding
    • Catch Weight UOM Group - Assign the unit to a group for organization

Verify the Setup

After setting up catch weights for an item:

  1. Open a Sales Order or Purchase Order
  2. Add the item to a line
  3. You should see an Alt. Qty. field next to the Quantity field
  4. The system will automatically calculate the alternate quantity based on your entry

Example Scenario

You have a beverage item sold by the case (CS) but tracked by the bottle (BTL):

  1. Open the Item Card for the beverage
  2. Set Alternate Unit of Measure to "BTL"
  3. Go to Item Units of Measure
  4. For the "CS" unit, set Qty. per Unit of Measure to 12 (12 bottles per case)
  5. For the "BTL" unit, set Qty. per Unit of Measure to 1
  6. Now when you sell 10 CS, the system automatically shows 120 BTL in the alternate quantity

Troubleshooting

The Alt. Qty. field doesn't appear in documents

  • Verify Catch Weight Management is enabled in Setup
  • Confirm the item has an alternate unit of measure configured
  • Check that your user has the NAVX CWM STANDARD permission set

The alternate quantity doesn't calculate correctly

  • Verify the conversion factor in the Item Units of Measure is correct
  • Check the rounding settings for the unit of measure
  • If using rounding, the calculated quantity may differ slightly due to precision
