Hyperspace enables you to sync your total stock for all stores to Shopify or select specific store locations to sync stock. In Account Settings > Web Store Settings you add your Shopify API keys for one or several locations in Lightspeed Retail.
Typically this setup is completed by your Hyperspace Project Manager.
In your Data Update Settings, further down on the settings page...
There is a setting called: Update Inventory of product with current Locations on Setting. This is asking whether you want to sync all stock or only sync from the locations that have added API keys.
Enable this if you want to only sync stock from specific locations.
Disable this if you want to sync from all locations in Lightspeed Retail and not exclude any specific locations.
