Missing items

Missing items is the page where you review products that Putaway WMS has temporarily separated as missing. They are held in the system area INVENTORY-MISSING, so they are not confused with stock available for normal work.

The page is for investigation and decision-making. It is not a normal physical location, not a daily scanning screen, and not the place operators pick or replenish from.

When To Open The Page

Open Inventory → Missing items when you need to check products reported as not found in the warehouse.

The most common situations are:

• after an inventory count where Putaway WMS moved missing differences into INVENTORY-MISSING;
• after picking, when the operator used Product missing for a product that was not found in the suggested location;
• after replenishment, when the operator marked a product as missing and the source location must be checked;
• when reports or the dashboard show missing stock and you need to find the cause.

Where Items Come From

From inventory counting

During inventory counting, if Putaway WMS expected a product in a location but the product was not physically confirmed, the difference is separated as missing.

This separation helps investigation: the product is no longer treated as normal stock, but its details remain visible for comparison, traceability, and reconciliation.

From picking

During picking, the operator should use Product missing only when the product is not physically present in the displayed location. At that moment, the quantity assigned for picking is separated into INVENTORY-MISSING and appears in Missing items.

This protects the flow: the unfound product no longer remains available as if it were still on the shelf, and the order can be sent back for resolution according to the picking process.

Before marking the product as missing, the operator must check the displayed location, barcode, lot, serial number, and handling unit.

From replenishment

During replenishment, Product missing marks the line in the replenishment list as missing when the product is not found in the source location.

Replenishment does not move the product into Missing items by itself, because this flow tries to move stock from one location to another, not to confirm a final stock loss.

After a replenishment shortage, check the source location. If the product is found, correct the replenishment process. If the shortage is real, handle it through stock check, inventory counting, or adjustment, so the difference is recorded correctly.

When This Page Is Not The Right Place

Products not delivered during supplier-order receiving are not warehouse missing items. They are goods ordered but not delivered by the supplier, and they are handled through Goods receiving and Goods receipt note.

Low stock does not move products into this page. It only shows that stock is below the configured threshold.

What The List Shows

For each item, the page shows the details needed for identification:

• product name;
• SKU;
• brand;
• quantity;
• scanned barcode;
• condition;
• lot and expiration date;
• serial number;
• supplier;
• handling unit, if any;
• acquisition price;
• inventory that generated the difference;
• last update date.

Filters

The page can be filtered by:

• search text;
• brand;
• supplier;
• lot.

Reset returns the filters to their initial state.

How To Use It

1. Search for the product by SKU, name, barcode, brand, supplier, or lot.
2. Check the quantity, system area, lot, serial number, and handling unit.
3. Compare with Traceability and Stock history.
4. If the shortage came from picking, check the location where the operator did not find the product.
5. If the shortage came from inventory counting, check the inventory that generated the difference.
6. If the product was found in another location, resolve the difference through reconciliation or the correct operational flow.
7. If the shortage is real, use adjustment or the internal write-off process.

Why Verification Matters

A missing item does not automatically mean the product is permanently lost. It may be:

• in another location;
• inside the wrong handling unit;
• scanned with another barcode;
• blocked in a started but unfinished flow;
• truly missing, in which case it must be written off through the correct process.

The page helps separate these cases before any final decision.

Rules

• Do not treat Missing items as available stock for orders.
• Do not manually move these products back to good stock without verification.
• Do not treat the page as final proof without traceability.
• Do not use the page as a replacement for inventory counting, picking, or replenishment.
• Do not confuse warehouse missing stock with sales low stock or supplier-undelivered goods.
