Setup

On ChannelEngine

Tesco is a Mirakl-based marketplace. Therefore, you use your Mirakl Connect SSO account credentials to connect ChannelEngine to Tesco. For more information on how to leverage your Mirakl Connect SSO account with ChannelEngine, check out the Mirakl-based channels: SSO authorization article.

Invoice uploads

To configure your invoice settings, go to Advanced settings. Then, select one option from the dropdown menu in the Enable invoice uploading field, which contains the following options:

• ChannelEngine invoices - when ChannelEngine receives a shipment, ChannelEngine automatically generates an invoice and attaches it to the shipment before exporting the shipment.
• Merchant invoices (optional) - when ChannelEngine receives a shipment, ChannelEngine exports the shipment – even if there is no invoice attached to it.
• Merchant invoices (required) - when ChannelEngine receives a shipment, ChannelEngine only exports the shipment if an invoice is attached to it. If not, you receive a notification.
• None - when ChannelEngine receives a shipment, ChannelEngine takes no action other than notifying you that no invoice is present.

If you select one of the Merchant invoices options, make sure to upload the invoice to ChannelEngine via the Merchant API or via the web interface. To learn more, check out the article ChannelEngine: upload merchant invoices.

Mappings

Content

All products (required)

The following required attribute is common to all Mirakl-based marketplaces:

• Export strategy - choose a strategy for exporting product data. You can select from the following export strategies:
  • Yes - export all product content to the marketplace, including the EAN (GTIN), category, and other mapped attributes. This option is ideal if you manage both product content and offers through ChannelEngine for the marketplace. Before you set this option, ensure that you map all required attributes.

  • No - do not export product content to the marketplace. Choose this option to keep the product content excluded from exports and only export the offers. This option is ideal if you do not want to export the product content yet, or you want to export only the product offers because the product content already exists on the marketplace.

All products (required)

If pricing v2 is activated in your environment, you will see the following offer attributes, which are common to all Mirakl-based marketplaces:

• Allow promotion below min price - set it to ‘true’ to allow the promotion price to drop below your product's minimum price. To learn more, check out the article ChannelEngine: promotions.
• Strike price - the regular selling price. Use it in combination with the Price attribute to set up a discount/strikethrough pricing. To learn more, check out the 'Working with discounts' section of this article. 
• Additionally, the Fee groups attribute appears in Mappings, Fee group mappings, if pricing v2 is activated. Map the marketplace fee group ID of the product there.  

The following offer attributes are also common to all Mirakl-based marketplaces:

• Discount start date - the date from which the product's sale price is valid, if applicable. Input the date as a fixed value. The date format is YYYY-MM-DD HH:MM:SS ZZ. All dates follow ISO month-day formatting, and all times follow 24-hour formatting in the UTC timezone. E.g.: 2026-10-25 15:30:00 +01 will start your discount on 25 October 2026 at 3:30 PM, one hour ahead of UTC time.
• Discount end date - the date until which the product's sale price is valid, if applicable. Input the date as a fixed value. The date format is YYYY-MM-DD HH:MM:SS ZZ. All dates follow ISO month-day formatting, and all times follow 24-hour formatting in the UTC timezone. E.g.: 2026-10-30 23:59:59 +01 will end your discount on 30 October 2026 at 11:59 PM and 59 seconds, one hour ahead of UTC time.
• Discount price - the product's sale price, if applicable. This attribute must have a lower value than the Price attribute. This attribute only applies if you use pricing v1.
• Discount quantity threshold - the minimum quantity required for the discount rate to be available.
• Leadtime to shipment - the number of days before you ship the product. You can create your own unique rules, if applicable. For more information on this, check out the article Lead time to ship in Mirakl's help center.

• Offer state - the product's condition. Find your option from the dropdown menu by selecting the fixed value to apply to all.
• Product tax code - the taxation code applicable to the product.
• Logistic class - your optional shipping class. Make sure to map the shipping class using the marketplace’s codes and not with the labels that are visible in the partner portal's user interface. These codes vary per marketplace. If this marketplace makes use of logistic class codes, they can be found below.

Logistic class codes

Carrier

Carrier mapping is not required on Mirakl-based marketplaces. However, with carrier mapping, you can map your carrier to a specific list of carriers maintained by this marketplace. Carrier mapping enables ChannelEngine to automatically send the tracking codes to this marketplace, allowing buyers to eventually track the shipment themselves. If your carrier is missing from the list, please directly contact the marketplace.

Pricing

Working with discounts

These instructions apply to most Mirakl marketplaces. If there are any exceptions on this marketplace, these are noted below. 

Pricing v1

• To set up a discount, map the Discount price, Discount start date, and Discount end date attributes. If you want to set a permanent discount, map the Discount end date attribute with a date in the far future instead of leaving it unmapped. Otherwise, the offer is not exported, and errors are shown on the Validation and feedback tab.
• The discounted price is only exported if it is lower than the base price.
• If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped.
• To set a bulk discount, the Discount quantity threshold must be set to a value higher than 1. For example, a value of 2 indicates that the buyer must purchase two or more products at the same time to benefit from the discount.

Pricing v2

• To set up a discount, in the Offer mappings step, map the Strike price attribute to your regular price. Then, map the Discount start date and Discount end date attributes to indicate the start and end dates of your discount.
• If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped. To learn how to set up a bulk discount, check out Bulk discounts.
• In the Pricing step, go to Price rules. Map the Price attribute to the discounted price. Both Min. price and Base price fields must be mapped. Note that ChannelEngine exports the higher of the two values – typically the Base price. To learn more, check out ChannelEngine: price rules v2.
• The Price and Strike price attributes cannot be mapped with the same value. ChannelEngine only sets a discount if the value in Price (Base price) is lower than the value in Strike price.
• If set up correctly, your product displays a discount label and a strikethrough price on the channel.

Listed products

If you have problems with products not appearing on Mirakl-based marketplaces – especially if you are trying to create products, check the Listed products page for more information. Use the Channel status filter or the Validation and feedback tab to view all known errors for specific products.

If you see either of the below statuses, refer to the article ChannelEngine: why is my product listed as 'Product not found' in the inventory report?:

• Product not found in inventory report
• Product not in offer file

Products that ChannelEngine has failed to export are shown as Invalid, e.g.: products with an empty GTIN or that do not yet exist on the marketplace.

Alternatively, download the error report generated by Mirakl. To do so:

1. Log onto the Mirakl platform and go to Catalog, Product imports.
2. Identify the latest report and click the See details button.
3. Download the CSV file Non-integrated products report.

Additional information

Order extra data items

When an order is imported to ChannelEngine, ChannelEngine also retrieves extra data items related to the order itself – or to order lines. This extra data is specific to this marketplace. An explanation of each can be found below: 

Order extra data

* Conditional fields are only displayed if the marketplace provides a value.

FAQs

How often does each task run on Mirakl-based marketplaces?
By default, Mirakl-based marketplaces follow the schedule below:

Can I map attributes on ChannelEngine and on the Mirakl platform?
No. Mapping attributes on the Mirakl marketplace platform interferes with ChannelEngine's content export. Therefore, it is recommended to categorize and map content only on ChannelEngine.

Why am I not receiving feedback on my content and/or offer exports?
Chances are that you are receiving the feedback. However, different types of error reports can take a couple of hours or several days to be generated:

• Offer feedback
  • Error reports are mostly generated automatically and are imported quickly.
• Content feedback
  • Transformation error report - this is automatically generated, and usually imported within a maximum of one day.
  • Conventional error report - this requires a manual review by the Mirakl-based marketplace, and not all do so. It can take several days for this report to be imported.

Note that the previous feedback report is not removed from ChannelEngine until both the latest transformation and the conventional reports have been fully processed by ChannelEngine. If there are no errors to report, no new reports are generated.
