Common error messages

Here are the error messages you are most likely to see in PO Flow and what they mean.

Missing required fields

One or more required fields on the PO are empty. The most common are Supplier and at least one line item with a positive quantity.

No items to receive

You opened Receive Stock but every line is set to 0. Enter a positive quantity on at least one line.

Could not find inventory level for item

Shopify did not return an inventory level for one of the items at the selected location, even after activation. Try a different location or confirm the variant exists at that location in Shopify.

SKU not found in Shopify

From the CSV import: an SKU-only row referenced an SKU that does not exist in your Shopify catalog. Fill in the product details on that row manually or fix the SKU.

Lookup failed for SKU

From the CSV import: the lookup hit a network error rather than a missing match. Re-import the CSV.

Reason is required

You clicked Delete Receipt or Correct Receipt without entering a reason. Add a reason and try again — it is recorded in the PO history.

Couldn't load purchase orders for this order

From the order-detail Shopify admin block: the call to PO Flow's backend failed. Reload the order page to retry.
