What Is Basic Mapping?
Basic Mapping pairs each store variant with a supplier variant — so DSers knows which item to order. You can assign up to two suppliers per variant (default + backup) and use different suppliers across variants of the same product.
What You Can Configure with Basic Mapping?
| Capability | What It Does | Example |
|---|---|---|
| Default Supplier | Primary supplier for a variant | Red t-shirt → Supplier A |
| Back-up Supplier | Secondary supplier used when default is unavailable |
Red → Supplier A & B
If Supplier A is out of stock → Supplier B
|
| Cross-mapping | Different suppliers for different variants of the same product | Red → Supplier A, Blue → Supplier B |
