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 categorised by type and reason code. Type denotes whether an adjustment is an increase or decrease to your inventory level. Reason code describes the adjustment made.

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

Date Transaction Item ID FnSku Merchant SKU Title FC Quantity Reason Disposition
March 24, 2019 13895071006 X0000COYXD 2Y-IQFY-RUQV How Deep Lies the Shadow LEJ1 -1 Damaged at Amazon fulfilment centre Sellable
March 24, 2019 13895071060 X0000COYXD 2Y-IQFY-RUQV How Deep Lies the Shadow LEJ1 1 Inventory disposition change Warehouse-damaged

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