Hello from Amazon Selling Partner Support,
I acknowledge your concern regarding reversal of the reimbursement ID: 17802079061 for FNSKU: X003UBESMN.
We notice that the FBA inventory below was received after reimbursement had been granted:
262.85 USD
This inventory is no longer missing, and your account has been debited to reverse the reimbursement. This appears as a negative Balance Adjustment in the Other portion of your Payments report.
To view the inventory added to your seller account, follow these steps:
Under the Reports tab in Seller Central, choose Fulfillment. Locate your Inventory Adjustments report in the menu on the left-hand side of your screen. In the Event Date dropdown list, select Exact dates. In the From: field, type or select the start date. In the To: field, type or select the end date. Click Generate Report. In the Reason column, locate Inventory found. The items with this reason code were returned to your inventory and the reimbursement has been reversed. If you download the report, filter on F in the Reason column to see the returned items. It can take 24 hours for data to populate in this report.
