Shopify recently added support for variant-level sales channel publishing.

We've pushed an update to EZ Exporter's Shopify product export so you can also now generate reports showing the list of sales channel names a product or variant is published/staged to be published to.

The following fields are now available when creating a Data Settings for Product data:

Product Level

resource_publications.publication.channels.handle	Product Publications Channel Handles (type: text). A comma-separated list of sales channel handles where the product is published or staged to be published.
resource_publications.publication.channels.id	Product Publications Channel IDs (type: text). A comma-separated list of sales channel IDs where the product is published or staged to be published.
resource_publications.publication.channels.name	Product Publications Channel Names (type: text). A comma-separated list of sales channel names where the product is published or staged to be published.

Variant Level

variants.resource_publications.publication.channels.handle	Variant Publications Channel Handles (type: text). A comma-separated list of sales channel handles where the variant is published or staged to be published.
variants.resource_publications.publication.channels.id	Variant Publications Channel IDs (type: text). A comma-separated list of sales channel IDs where the variant is published or staged to be published.
variants.resource_publications.publication.channels.name	Variant Publications Channel Names (type: text). A comma-separated list of sales channel names where the variant is published or staged to be published.

These fields are also available under the Custom Filters section of the Data Settings, so you can also generate reports of products/variants that are published to specific sales channels.
