Why can't I save a purchase order with a non-inventory product line?

What you will see

When you save a purchase order that has a warehouse, Luminous checks every line. If a line is a Non-Inventory product, the save is rejected with a message like: "This purchase order can't be saved: line 2 is a non-inventory product, which cannot be a purchase order line. Remove it or record it as an extra cost." The message gives the line numbers. Nothing is saved when this happens.

Why

Non-inventory products don't get a receiving stock location, so a PO line for one can't be received. In the past, such a line was silently skipped. The PO header still counted it, so the item count and total didn't match the saved lines.

What to do

1. Remove the listed line(s) from the PO.
2. Record the cost as an extra cost on the PO instead.
3. Save again.

The same check applies when the in-app AI agent edits a PO.

Notes

• POs that have no warehouse (for example dropship POs) keep non-inventory lines.
