This error means Target+ has taken your listing (TCIN) offline because Target has decided that the product's UPC will be listed by another source. Target allows only one active listing per UPC, so while another source holds that UPC, your item stays unlisted.
The error isn't caused by missing or incorrect product data in Acenda. The conflict lives in Target's catalog, so Acenda can't clear it for you. It's resolved with Target+ Partner Support or your Target+ Category Manager.
The error you'll see: DATA_VALIDATION: TCIN has been unlisted as the UPC will be listed by another source.
Where you'll see it
Item Issues: In the sidebar, under CHANNELS, click Item Issues. The error is listed with the item's SKU and a Source of channel, which means it came from Target. The Attribute Path column shows unknown, because Target doesn't tie this error to a single attribute.
On the item: In the sidebar, under CATALOG, click Items, click the eye icon next to the item, and open the Channel Status tab. Click the Target+ tab (or whatever you've named your Target+ channel). The status shows UNLISTED. The item's TCIN still appears under View on Channel, and your Listing Action doesn't change.
To check what Acenda last sent to Target+ for the item, see Tracking Marketplace Updates with Channel Events. Channel Events show what Acenda sent, not Target's reply. Target's decision appears in Item Issues.
Why it happens
Target doesn't tell Acenda who the other source is, and only Target can confirm it for your item. Based on what sellers have heard back from Target, it's usually one of these:
Target sells the product itself: The UPC is part of Target's own assortment, in stores or on Target.com.
Another Target+ seller: A different partner lists a product with the same UPC, and Target has chosen their listing.
Your own other listing: In rare cases the other source is you. If you changed the item's SKU in Acenda, Target can treat the new SKU as a new product with the same UPC as your existing listing. See Can I Change SKU Values for My Marketplace Listings?
How to fix it
Gather the details. Note the item's SKU and UPC (on the item's Details tab) and its TCIN (on the Channel Status tab, under View on Channel). If several items are affected, export your TCINs instead of copying them one by one.
Check for a recent SKU change. If you changed this item's SKU, follow Can I Change SKU Values for My Marketplace Listings? and Understanding Aliases to point the item back at your original Target listing before you open a case with Target.
Confirm you own the UPC. Check that the UPC is registered to your company with GS1, or licensed to you by the brand owner.
Contact Target. Log in to the Target Partner Portal and open a case with Target+ Partner Support, or reach out to your Target+ Category Manager. Include the TCIN, SKU, UPC and the full error text, and ask who holds the UPC in Target's catalog and whether your listing can be reinstated.
Act on Target's answer.
If you own the UPC: Send Target proof of ownership, such as your GS1 certificate, and ask them to reinstate your TCIN.
If you don't own it, or Target won't release it: You can't sell this item on Target+ under that UPC. If you have a genuine GS1 UPC of your own for this product, ask Target whether you can use it, then update the item's UPC (see below).
Check the Listing Action. Once Target confirms the fix, open the item's Channel Status tab and make sure the Target+ Listing Action is Full. Acenda sends the item to Target+ with its regular updates, Target reviews it, and the error clears in Acenda once Target relists the item.
To change an item's UPC: In the sidebar, under CATALOG, click Items, click the eye icon next to the item, and on the Details tab update the UPC field, then save. For an item with variants, change the UPC on the variant itself, not on its parent. Acenda sends the change to Target+ automatically with its next update.
Important: Never use a made-up or borrowed UPC. Changing the UPC can create a separate product at Target, so check with Target+ Partner Support first. If the new UPC already belongs to another product, you'll see the error in Error FAQ: Duplicate Barcode at Target+ instead.
How to prevent it
Use only GS1 UPCs registered to your company, or licensed to you by the brand owner, and keep the certificate or license handy.
Before you list products that Target already sells, or that other sellers may carry, ask your Target+ Category Manager to confirm you're approved to list those UPCs.
Don't change the SKU of an item that's already live on Target+. Use an alias instead, as described in Understanding Aliases.
Troubleshooting and FAQ
I own the UPC, but my item is still unlisted. Owning the UPC doesn't release it automatically. Target has to reinstate your TCIN. Send Target+ Partner Support your GS1 certificate (or the brand owner's license) and ask them to reinstate the listing.
I changed the UPC, but nothing happened. Check that you changed it on the variant and saved. Target then has to review the item again, which can take time. Look in Item Issues for a new error on the item, such as a duplicate barcode. If nothing has changed after a couple of days, contact Acenda Support with the SKU and TCIN.
Can I relist the same item? Not from Acenda alone. Switching the Listing Action or re-sending the item won't override Target's decision. The TCIN stays unlisted until Target reinstates it.
Does this affect my other variants? Target unlists by UPC, so usually only the variant with the conflicting UPC is affected. Check each variant's Channel Status tab. If several are unlisted, list all of their UPCs in your case with Target.
How long does Target take to respond? That's up to Target+ Partner Support, and Acenda can't speed it up. Follow up on your case in the Target Partner Portal if you haven't heard back.
I see "Suspended: Item is going to be supplied by another source" instead. It's the same kind of conflict, but Target has suspended the item rather than unlisting it. Only your Target+ Category Manager can lift a suspension, and changing the Listing Action won't help. Once Target lifts it, contact Acenda Support with the SKU so we can re-send the item.
How is this different from the duplicate barcode error? A duplicate barcode error stops a new listing from going live. This error takes an existing listing offline. See Error FAQ: Duplicate Barcode at Target+.
My item was unlisted for having no sales. That's a different error. See FAQ: Troubleshooting the "Unlisted Item" Error (Target+).
