This tab lists items in your ERP where two or more Retailer SKUs share the same Manufacturer SKU. This is a critical issue: when the data feed encounters a duplicate Manufacturer SKU, it cannot determine which ERP item is the correct one, which means the wrong price or inventory quantity may display on your website.
⛔ This Is Your Highest Priority Issue
Duplicate Manufacturer SKUs cause direct, visible errors on your website. A customer may see the wrong price or an incorrect stock status for a product. These should be resolved before working on any other tab.
Understanding the Columns
| Column | What It Means |
| Retailer SKU | The ERP item number for each item sharing the duplicate Manufacturer SKU. |
| Mfg SKU | The Manufacturer SKU that is duplicated across multiple Retailer SKUs. |
| Duplicate Mfg SKUs | The total count of items sharing this Manufacturer SKU. |
| Qty In Stock | Current on-hand quantity for each item. |
| Discontinued Status | Items marked as discontinued are often the source of duplicates (an old HB item alongside a new one). |
How to Resolve Duplicate Mfg SKUs
For each set of duplicate SKUs, you need to determine which Retailer SKU is the correct one and fix or remove the Manufacturer SKU from the others:
- Identify which of the duplicate Retailer SKUs is the correct, current item (usually the one with stock on hand and no discontinued status).
- For the other item(s) in the duplicate set, go into your ERP and either correct the Manufacturer SKU to the right value, or remove it entirely if the item is discontinued and has no stock.
- If one of the duplicates is a discontinued item with zero stock, the simplest fix is to delete the Manufacturer SKU from the discontinued item.
💡 Tip: Look at the Discontinued Status column first. In most cases, one item in the duplicate pair will be marked as discontinued — that is almost always the one to correct or clear.
