Special Scenario's
Variants
When setting up the Variation, there is a tickbox "Quantity varies with Variation"
If you have selected this, you'll only need to map one Luminous SKU to a single variant. ETSY will automatically keep all variants in sync.
If you haven't selected that tickbox, you can connect each variant in ETSY to a unique sku within Luminous.
In both cases, you'll not want to connect the master sku to anything within Luminous.
