Use this workflow to create an outside-service Purchase Order from work order outside-service steps.

When to use this workflow

Use this workflow when a work order needs outside-service work performed by a vendor.

Use the generated PO instead of manually creating unrelated PO lines so PAX can keep outside-service cost tied to the work order.

Before you start

Confirm:

  • The work order exists and is in Draft, Released, or In Progress status.
  • The router includes an Outside Service operation.
  • The vendor exists in Vendor Management.
  • Required date and payment terms are known.
  • Unit price is known for each selected outside-service step.

Steps

  1. Go to Dashboard > Purchasing > Purchase Orders.
  2. Select Outside Service PO.
  3. Select the Vendor.
  4. Confirm PO Date.
  5. Enter Required Date.
  6. Select Payment Terms.
  7. Review the listed work orders.
  8. Expand any work order that has more than one outside-service step.
  9. Select each outside-service step that should be included on the PO.
  10. Enter or confirm the Unit Price for each selected step.
  11. Review the selected step count.
  12. Select Generate PO.
  13. Review the generated PO when it opens.

Unit prices

PAX suggests a unit price only when it can determine one from the work order's BOM structure. If no suggested price is available, enter the correct unit price manually.

PAX warns if selected lines have a unit price of zero. Continue only when a zero-price outside-service line is intentional.

What happens behind the scenes

PAX creates an issued Purchase Order with one line for each selected outside-service step.

PAX excludes operations already tied to active PO/work-order links so the same outside-service work is not selected twice.

Generated lines are linked to the work order and outside-service operation sequence. PAX forces the line to WIP account 1210 and treats it as non-inventory for normal inventory tracking.

The generated PO opens in the Open Purchase Orders editor after creation.

Creating the outside-service PO does not receive the service, post the outside-service cost to the work order, or close the work order. Receiving the PO later records the received outside-service quantity and updates work order outside-service cost behavior.

Troubleshooting

No open work orders with Outside Service steps found

Likely cause: No eligible work orders have outside-service operations, or eligible operations are already tied to active PO/work-order links.

Safe fix: Review the work order router and active PO/work-order links.

Contact support if: A valid outside-service operation should appear but does not.

Please select a vendor

Likely cause: The vendor field does not match an exact vendor option.

Safe fix: Search and select the vendor from the dropdown list.

Contact support if: The vendor exists but cannot be selected.

Please select at least one Outside Service step

Likely cause: No step checkbox is selected.

Safe fix: Expand the work order if needed and select the correct operation.

Contact support if: Step selection does not stay selected.

Zero-price warning appears

Likely cause: One or more selected steps has unit price 0.00.

Safe fix: Enter the correct unit price, or continue only when zero cost is intentional.

Contact support if: Suggested pricing should populate but does not.
