eBay's Large Merchant Services not returning a SKU

Question

I am specifying a SKU in my AddFixedPriceItem requests but the response does not come back with a SKU (although SKU is specified in the schema). This is a problem because I am using Large Merchant Services and can submit many items at once. If one item in a batch fails, how am I supposed to be able to tell which one it is? How can I relate SKUs to ItemIds? The response information has very little value if I can't map it back to something in my inventory.

Here is an example of a request going out that does not return a SKU:

If one item in a batch fails, how am I supposed to be able to tell which one it is?

Use MessageID in your AddFixedPriceItem Request.

How can I relate SKUs to ItemIds

Most likely I'm assuming you're wanting to manage your inventory via SKUs, i.e. "Increase Quantity by +2 for SKU 'MYTESTSKU02'. If this is the case, you'll want:

<InventoryTrackingMethod>SKU</InventoryTrackingMethod>

Then you can Relist/Revise/End by SKU. If you merely wish to associate a SKU to an ItemID as more of a label and you still desire to manage your inventory by ItemID, then your current request seems correct.

In terms of the SKU field not being returned, can you paste the AddFixedPriceItemResponse?
