If your Shopify listings do not appear to be syncing stock to Shopify, or your sync reports show error logs indicating:
This item is not connected to location XYZ. SKULabs can optionally connect items to locations in Shopify. See your store settings in SKULabs under integration options."
Error: This item does not manage inventory at location XYZ please see https://help.shopify.com/en/manual/products/inventory/track_inventory#set-up-inventory-tracking
the most common cause is that your Shopify inventory tracking has recently been changed on your channel, but you have not yet run a listing sync to update the listing within SKULabs.
How to correct:
Start by simply running a listing sync for this store. After listings sync runs, allow some time for stock sync to run, then check if stock is now successfully being pushed for the affected SKUs.
It is always recommended to run a new listing sync after making any changes to products on your sales channels, including Shopify stock locations.
Listings sync is important to some Shopify stock sync related issues. Listings in SKULabs require up-to-date information about the locations that a product/variant is assigned to on Shopify for real time stock sync pushes to be accepted by Shopify successfully. If you've updated or recently changed the locations where products/variants can be found on Shopify, listing sync will import those changes and keep your listings up-to-date.
Note: you can automate running listing syncs periodically from your Settings > Advanced > Scheduled Automations.
If this does not resolve the issue, please reach out to support in chat with the SKU of the product and screenshots of the product's details page including inventory levels on Shopify.
