Inventory adjustments

The Inventory Adjustments report shows the history of adjustments to your inventory in response to issues such as disposition changes, misplaced inventory, found inventory, and ownership corrections.

Adjustment types and reason codes

Inventory adjustments are categorized by type and reason code. The type shows whether an adjustment is an increase or decrease to your inventory level. The reason code describes the adjustment made.

Inventory adjustments often occur in pairs. For example, if your inventory changes disposition from sellable to expired, there will be two adjustments to your inventory: a decrease in your sellable inventory and an increase in your expired inventory. Here is an example:

Date Transaction Item ID FNSKU Merchant SKU Title Disposition FC Reason Quantity
March 24, 2019 13895071006 X0000COYXD 2Y-IQFY-RUQV How Deep Lies the Shadow Sellable LEJ1 Inventory disposition change -1
March 24, 2019 13895071060 X0000COYXD 2Y-IQFY-RUQV How Deep Lies the Shadow Expired LEJ1 Inventory disposition change 1

The following table lists all inventory adjustment reason codes and their type.

Code Type Reason Definition

Q - Inventory disposition change Units of a certain disposition are removed from your inventory and then added back to your inventory as a different disposition. This is always followed by a P code adjustment.

Inventory dispositions

Inventory disposition represents the physical state of a unit or units.

How to read your report: online and download methods

You can see adjustments to your inventory online in Seller Central or by downloading the Inventory Adjustments report.

  • The View Online method is recommended for quickly seeing inventory adjustments and reconciliations. When there is a reconciliation for an inventory adjustment, a link is provided that will connect you to either the reconciliation adjustment in the Inventory Adjustment report or the reimbursement transaction in the Reimbursement report.
  • The Download method is recommended for understanding the reconciliation status of inventory adjustments at scale.

In the online view, you can filter inventory adjustments by Reason group, as shown in the table below.

Reason groups by adjustment code

Code Reason group

Why are my items being researched?

You will notice a new inventory classification in the Manage Your Inventory page and report, called Researching. This represents the misplaced or warehouse damaged inventory that is actively being confirmed at our fulfillment centers. A timeline shows the duration of the research, which will never exceed 30 days. Once the inventory being researched has been reimbursed or has exceeded the 30-day duration, you will see the corresponding adjustment transition over to the Inventory Adjustment report. For inventory adjustments occurring after November 15, 2019, you do not have to wait 30 days to file a claim because we are handling the 30 day researching duration for you.
