Filters the response to only include order line items for listings that match this InventoryTrackingMethod setting.
To track items by seller-defined SKU values instead of by Item IDs, the InventoryTrackingMethod must be included and set to 'SKU' in the AddFixedPriceItem (or ReviseFixedPriceItem or RelistFixedPriceItem) call.
You can combine SKUArray with InventoryTrackingMethod. For example, if you set this to SKU and you also pass in SKUArray, the response only includes order line items for listings that include InventoryTrackingMethod=SKU and one of the requested SKUs.
See the
Field Index to learn which calls use InventoryTrackingMethod.
