If a seller is not having unique sku’s i.e. same product has been listed with different sku’s on different portal,
Then the seller is required to have unique skus to manage his inventory through Vin eRetail Express.
For e.g. Seller is having a maroon wallet and it has been listed with sku Wallet on Paytm, With channel sku as Wall on flip kart, And with W1 as channel sku on Amazon,
In such a case, select the major channel sku as the unique sku,
**Major Channel: A channel where most of your sku’s are listed and the seller gets most of his orders from that Marketplace**
Let us suppose in this example Paytm was the channel where 60% of your total products were listed and you are getting a greater % of orders from that MP,
Now when you have created your unique sku’s from Paytm,
Then 60% of the unique sku’s are created and one major channel is mapped,
Map the rest of the channels and upload the data in the panel.
**Going ahead make sure to make a product live on every MP with the unique sku only as
It will help you to manage your inventory easily**
