To ensure you upload a valid set of product data, you can create a list of products in your own PIM system and configure the list afterwards via the Mirakl backend. Choose this solution if you supply a large range of products that comprises many different items.
The advantage of uploading your own product list via the mapping wizard is that you only need to do the assignment once to make it known in Mirakl. Now the system automatically recognises previously assigned categories in any file you upload.
In case you add new categories, attributes or values you need to edit existing mapping. To add them correspondingly it's recommended to upload a current file newly to the Mirakl Mapping Assistant.

1. Import Product Data File

Go to  “Settings" -> “Catalog mapping” (on the menu bar.) There on Top it displays the “mapping wizard” tag.

• Upload your own product list as a UTF-8 encoded XLSX or CSV file here.

2. Choose Categories

After uploading the file, you will be asked to select categories.

• Select the column name that matches your product category.
• If you use subcategories, you also need to enter the character you use to separate the different levels in the field called “Subcategory separator (optional)”.

The same window displays a preview of the uploaded file using the assigned column names.

3. Assign Categories

The next step involves assigning categories. Your chosen categories levels are shown on the left. The format required by Conrad is displayed on the right. 

• Use the two crossed arrows in “Root” to automatically assign your categories to Conrad categories with the same name.
• Any remaining categories need to be assigned manually using Drag & Drop.

• If you click “Assign”, categories highlighted in grey represent those that have already been assigned.
  You also see where they have been assigned to.
  You can unassign categories by clicking the “X” shown next to them.

4. Assign Attributes

This step involves assigning (mapping) attributes.

The “Automap” button at the top enables mapping attributes with the same name.
Attributes that don’t match your configuration need to be manually assigned.

Mandatory attributes are shown in red and are required for creating accurate product master data. 

The summary on the left screen side tells you how many attributes still need to be assigned.

• Scrolling to the bottom of the page prevents you from missing a mandatory field.

5. Assign Values

Based on the mapped values, you now need to assign values.
Click the blue button to auto-assign values with the same name.

• If you want to view current assignments, click the button next to "Unmapped values only"
• You want to reverse mappings:  then “X” to unassign values.

Values that cannot be auto-mapped need to be assigned manually.
Choose your value (left) and then click the respective value provided by the system (right).
You can also look up system values by using the “Search value” field.

6. Set Rules

This step allows you to create rules that apply to changing and validating assigned attributes, for instance, the minimum number of characters a MPN needs to contain.
(optional)

7. Summary and Validation

Finally, we’ve also got a page that shows you a summary of the mapping process. In the case there’s been a problem with an individual assignment, a link displayed below the respective field allows you to go back to any of the previous steps, such as category mapping, to resolve the issue.
To do this, you can use the Mapping Assistant at any time. 

• Afterwards, click “Import products” to upload your product data.

Then, as described in the article “Upload product data”, check the import and eliminate any errors.
