  • The client is an international company who has “-” sign in all their SKU’s and they cannot be changed.
    Trying to created a product with sku for example: 123556-abcssg
    results in a “SKU must be unique” error. Removing the “-” solves the problem but isn’t acceptable for the client.
    Please help, thanks!
