Use this workflow to manually add a new inventory lot with quantity and cost components.

When to use this workflow

Use Add New Lot when a new lot needs to be added manually through an inventory adjustment.

Do not use this workflow for normal purchase order receiving or finished-good work order completion. Those workflows create inventory lots through their own process.

Before you start

Confirm:

  • The part already exists.
  • The new lot number is known.
  • The lot does not already exist for the part.
  • Quantity is known.
  • Cost components are known.
  • Expiration date is known when the part has shelf life tracking.
  • The reason explains why a manual lot add is appropriate.

Steps

  1. Go to Dashboard > Inventory > Adjustments.
  2. Set Adjustment Type to Add New Lot.
  3. Enter or select the Part Number.
  4. Enter New Lot.
  5. Enter Expiration Date when the part has shelf life tracking.
  6. Enter Quantity.
  7. Enter Material Cost.
  8. Enter Labor Cost.
  9. Enter Overhead Cost.
  10. Enter Outside Process Cost.
  11. Review Total Cost per Unit.
  12. Enter a clear Reason.
  13. Select Submit Adjustment.

Cost fields

Total Cost per Unit is calculated from:

  • Material cost.
  • Labor cost.
  • Overhead cost.
  • Outside process cost.

Use the correct cost components before submitting. Cost entered here affects inventory valuation.

What happens behind the scenes

PAX creates a new inventory lot record for the selected part.

PAX inserts an inventory adjustment record with adjustment type AddNewLot.

If quantity times total lot cost is greater than zero, PAX posts the value impact to GL using the inventory adjustment posting configuration for the part's product line.

Troubleshooting

Expiration date is required

Likely cause: The selected part has shelf life tracking.

Safe fix: Enter the correct expiration date before submitting.

Contact support if: The part should not require expiration tracking.

Lot already exists

Likely cause: The entered lot is already present for the part.

Safe fix: Review the existing lot in Inventory Lot Detail Overview. Use another workflow if quantity or cost needs correction.

Contact support if: The existing lot record appears incorrect.
