Now I am more confused - I see a damaged item, and it is clearly yet another victim of the STUPID PAPER BAGS that amazon uses, so I need to rebut Amazon’s claim of “customer damaged”, when the return reason is “arrived damaged”.
I need to be able to link returns to reimbursements to make sure that I do not complain about orders where Amazon correctly admitted that they caused the damage, rather than blaming the customer. This has nothing to do with A-Z.
It has nothing to do with AtoZ.
It also has nothing to do with SAFE-T claims.
You need to file a reimbursement claim through seller support, but there is no way to tie an item to an order. Amazon does not give you that information. Amazon can look that up with the LPN, but we can’t.
Then how do I tie “customer damaged” claims by Amazon to the customer comment / return reason “arrived damaged”???
You can’t.
I go through the items Amazon returns to me and assess them without any idea what the return reason was. Anything that looks off, negligent, deceptive, or thievy, I file a claim. LPN, pictures of the item, pictures of a new, non damaged item for comparison when relevant, which it usually is.
Can’t you look up what order the LPN belongs to by going to Reports>Fulfillment>FBA Customer Returns and putting the LPN number in the LPN field?
Why, so you can!
Reports are not my thing.
@MissMeliss posted how.
EDIT:
To be honest though, I’m not sure this changes anything unless you want to file reimbursement claims for the return shipping on undamaged items that buyers say is damaged for free returns. This isn’t always true, but for most orders that isn’t worth my time. I guess it depends on what you sell, and how high your return rate is.
Hi @ZaphodBeeblebrox ! I moved this useful FBA conversation to its own topic so that it wouldn’t get lost. Thanks @MissMeliss and @HobbesIsMyTiger for chiming in!
I remember @selg (I think?) describing these when I was only ever seeing a paper/bubble layer combo envelope. But since a couple of warehouses have opened nearer to us and enabled faster delivery, we mostly now see what really are “just” paper bags–no thicker, no layers, and all full-frickin-paper-bag sized no matter the contents. 
So it seems that as Amazon expands its FBA footprint and delivery logistics, FBA Sellers could see more of these types of damages because Amazon is somehow appraising too many products as “safe” in a paper bag folded at the top.
