On SKU Mapping page, you can check whether the store SKU has been mapped with merchant SKU or not, and you can create/modify the mapping relationship between store SKU and merchant SKU.
This article would introduce five methods to set mapping relationships.
- Method 1: Manually Mapping
- Method 2: Auto Mapping
- Method 3: Modify Mapping Relationship
- Method 4: Import to Create Mapping

1) Generate Single SKU
- For example: if you select Shopee product "Book001" and Lazada product "Book002" and Shopify product "Book003", and set "Book002" as the standard product, when you click generate single SKU, it will generate a merchant SKU "Book002" for the above three products and map them.
2) Generate Combination SKU
- You can select multiple products and click this button, it will generate a combination SKU for the selected products.
3) Map current SKU
- Select one product or multiple products to map the existing merchant SKU.
💡 Notes
- Quickly Mapping Merchant SKU page only shows the unmapped products;
- The merchant SKU you generated is the same as the store SKU of the standard product by default;
- Please set the parent SKU or SKU before you do the SKU mapping. (optional)
