Fix it: warehouse messages and what to do
Last updated October 23, 2026
Short answers, grouped by where you see them. Messages are shown as the screen shows them; X stands for a slot code. The type of stock still has to match What lives in the warehouse.
Stock page
Pick a warehouse to edit stock
You run more than one location and the Stock page is on the totals view. It is the sum of your locations, so it is read only. Pick one warehouse, then edit.
This blank is tracked by bin, so its count comes from its bins
A typed on hand is refused because the bins are the count. The message ends Change it with Set locations, a putaway, or a count. Change the bins instead, or click Stop tracking by bin first. See Track by bin.
Received blanks do not show in on hand
The blank is tracked by bin and the putaway is still open. On hand rises only as units are placed. Finish the putaway on Inventory → Tasks.
Set locations
Cannot flip while open work orders reference this SKU
An open putaway, pick, or count list lists this product. Finish it or remove it, then save again. The same cause gives Cannot change locations while open work orders reference this SKU on a placed product and Finish or cancel the open tasks for this item before you stop tracking it by bin when you click Stop tracking by bin.
N units unaccounted for. What happened?
The placed total does not match on hand. Pick a reason and save, or fix the quantities so they add up.
Location X not found, or Location X is retired
The code is not on this floor or the slot was retired. Pick another slot. Some bin codes were not found. Nothing was saved. means the same for a list of codes.
Putaway
Line is already complete
That line was finished already, often by a second tap or a teammate. Nothing was added twice. Refresh and move to the next line. Line is already being completed means the first tap is still saving.
Enter the quantity placed, or a variance reason if the units are missing
You entered 0 and chose Keep the rest open. Keeping the rest open needs at least one unit placed. If nothing is there, choose a variance reason instead.
Scan or choose a location before completing.
The line has no suggested slot. Pick one from the list or scan a bin code.
No suggested locations to complete.
Complete all as expected only shelves lines that have a suggested slot. Choose slots for the rest one by one.
Units vanished after I removed a putaway
They did not. Units that were never shelved open again on a new putaway task. Look for it in the Putaway filter.
Mixed slot or owner
| Message | What it means |
|---|---|
| X holds house stock; cannot place seller goods here | One owner per slot |
| X holds seller stock; cannot place house goods here | Same, the other way round |
| X is reserved for another seller | Two sellers never share a slot |
| X already holds another seller's stock | Same |
| X already holds blank stock, or already holds seller stock | Blanks and seller goods never share |
| X holds stock with no owner. Assign or move it before putting more here. | Old stock on that slot has no owner |
Pick an empty slot or one that already belongs to this owner.
Tasks
Task is expired
Only pick lists expire. An open pick older than 24 hours is expired the next time a pick is generated, and its held units go back to available. Generate the pick again from the batch. Putaways and count lists never expire.
Exception lines are not actionable
The pick could not find that item on any slot, so the line cannot be completed. Put the stock away, then generate the pick again.
Bulk bay no longer has enough stock
The bulk slot on a restock has less than the move. Click Bulk empty, or lower the quantity.
No pick faces below minimum with bulk stock to pull. Nothing to restock.
No pick face has dropped to its minimum, or there is no bulk stock to move. Nothing is wrong.
Enter a reason for removing this task.
Remove needs a reason of at least three characters.
Counts
Someone other than the first counter needs to do this recount
The recount is at or above your second person setting (5 units unless you changed it) off the system number. Someone else must recount. The setting is under Settings → Inventory → Warehouse → Bins → Counts.
Someone other than the counter needs to approve this
A large difference can only be accepted by someone who did not count it. Ask a teammate to click Accept count, or click Keep system.
Enter a count for every location before submitting.
Every open line needs a number. Recount every flagged location before submitting. means the same for blind recount lines.
No locations with stock to count. Nothing to generate.
No slot has a product on it yet.
Batches and picks
No stocked/premade lines in this batch to pick
The batch has only print lines. Print lines never go on a pick.
Pick task generation already in progress for this batch
Someone clicked Generate pick task (stocked) at the same moment. Wait a few seconds; the open pick is reused.
20 printing from new stock
Batch item details shows, for example, 30 from stock, 20 printing from new stock. The batch took what was on hand and the rest is still needed. Buy it with Import from Batches on a purchase order. If the shelf really holds more than Riverr shows, fix the count with a count list or Set locations (or finish the putaway). Seller stock and house retail are never consumed as blanks.
Seller cannot send inventory
| The seller sees | Fix |
|---|---|
| Request sent. | Approve them under Waiting on you on 3PL → Sellers |
| This needs N more bins than you have. | Give them more space with Change space, or answer their space request |
| A required question on a product (size, weight, or barcode) | They answer it once on Send inventory. Your rules under What we accept from sellers decide what is asked |
| New shipments are paused | Click Resume on 3PL → Sellers |
See Send inventory to the warehouse.
Accept or decline this shipment first.
The shipment is Needs your OK. Click Accept shipment or Decline on the shipment before counting. Review the flagged products on this shipment first. means a product under Check before counting still needs Approve or Decline. See Receive a seller shipment.
Inbound is blocked
The floor is at the stop level, or seller stock fills every bin not held for house stock. See Capacity.
Open variance
Your count already posted. Follow up from Inventory → Receiving → Variances, then Resolve it with a note. See Resolve an intake variance.
Looking for Hold as stock
That batch menu action is gone. Print to shelf is a Stock order on the manual order page, with owner House or Seller.
Seller wants to place their own stock order
Stock orders are placed by you, on the seller's account. See Place a stock order for a seller.
