If your Profit & Loss Report is missing fees for a past settlement period (Inbound Shipping Fees, Storage Fees, etc), it could be due to reports that are missing inside of Seller Central. The most common missing report is the XML version.
To check, go to your Reports>Payments>All Statements page in Seller Central.
On the left side of the page, locate your CLOSED settlement periods (only).
You will see Download Flat File, Download Flat File V2 & Download XML to the far right of those periods
If correct, it should look like this:
If you do not see all 3 file types, please open a case with Seller Support and explain to them which types of files you are missing (XML, Flat File, or Flat File V2) and what settlement periods you need them to be available for. If the agent you get states they can only turn the reports on going forward, please ask to have your case escalated. They can generate missing reports for past settlement periods.
Once they get your account corrected and these reports available, our systems will automatically pick them up and get the data synced within 72 hours. :)
