If you need to modify an existing category mapping for a product, you can do so as follows:

  1. Go to the Products Mapping page from the Dashboard. (i.e click "Map Now" from the dashboard)

  2. Search for the product you wish to change/delete the mapping of.
    e.g. enter key words and filter by 'Show mapped'

  3. Once you have found the product, click the "delete" link next to it.

    This will delete the mapping and the product will then be available for mapping again.
