You can now use the Live preview function in the Mapping menu of a catalogue under Data » Catalogues to preview which values are exported to a marketplace using the current mapping settings.

Activate the Live preview toggle and then enter the name or ID of a variation in your system in order to display what values of that variation are exported for each mapping.

Important: The Live preview is only available for marketplace catalogues with the export types Item and Item (new) that support the Preview function. The Live preview is not available for standard formats (e.g. Manufacturers).
