Confirming and Mapping Your Master SKU
Summary
Step 2 of onboarding: confirm each imported listing is linked to a Master SKU, or map any that are missing, using bulk CSV import or manual per-listing linking.
In step 2 of onboarding you confirm that each imported listing is linked to a Master SKU, or map any that are missing. A Master SKU is the product identifier that ties a channel listing to a product in your catalog.
- Check Listings: a green circle marks a mapped Master SKU; a red circle marks a listing still missing one.
- Import Master SKUs: export the unmapped listings, fill in Master SKU values in the CSV, and upload to map in bulk.
- Manual linking: link or create a product per listing from the Product Link section.
- Onboarding step 2: clearing all Master SKUs lets you advance to step 3 in the onboarding flow.
Import Master SKUs (bulk)
Channel Listings → Actions → Import → Master SKUs. Select the channel, Export Listings (it auto-selects listings missing a Master SKU), fill the Master SKU column in the CSV, then Upload and Import.
Manually set (per listing)
Channel Listings → filter “Missing Master SKU” → open the listing. In the Product Link section click Select/Create Product, link an existing product or click New Product, then Save Variant.
| Header | Role |
|---|---|
| SKU | Required. The listing SKU being mapped. |
| Master SKU | Required. The Master SKU value to assign. |
| UPC, MPN, ASIN, Title | Populated for identification only. These do not update through the Import Master SKUs tool. |
Import Master SKUs completed without errors but the links did not update
Confirm the file used the exact case-sensitive headers SKU and Master SKU and that you selected the correct channel. The Master SKU import resolves to parent Master SKUs, so it cannot re-point a listing variant to a specific sibling variant under the same parent: that scenario needs the Product Link picker or support help.
A listing variant is linked to the wrong product variant and Re-Build will not fix it
Re-Build keeps existing link connections, so it cannot change the linked product variant. Use Select/Create Product in the Product Link section to relink. For multi-variant or bundle listings where the picker only resolves to the parent, contact support to correct the variant-level link.
How do I tell if a listing is mapped?
Look for the circle icon next to the product: green means the Master SKU is mapped, red means it is missing.
What columns does Import Master SKUs need?
Only SKU and Master SKU, and the header names are case-sensitive.
Will UPC, MPN, ASIN, or Title update through this tool?
No. They are shown for identification only and are not changed by the Import Master SKUs tool.
How do I set a Master SKU manually?
Open the listing, go to the Product Link section, click Select/Create Product, link or create the product, and Save Variant.
Why did Re-Build not fix my link?
Re-Build maintains existing link connections by design. Use the Product Link picker to change which product a listing is linked to.
How do I confirm that a Master SKU mapping is active and working?
You can verify the status of a mapping by looking for the circle icon next to the product in the Channel Listings view. A green circle indicates the Master SKU is successfully mapped and active, while a red circle indicates the listing is still missing a link. Once mapped, the Master SKU value will appear in the Product Link section of the listing details, confirming that Flxpoint can now synchronize inventory and pricing data between that channel listing and your Master Catalog.
