Find the answer to your question
will we get multiple records for a single sku if SKU array is specifed in GetSellerList request?
One active item will be returned in GetSellerList response for a single SKU if both <InventoryTrackingMethod>SKU</InventoryTrackingMethod> and <SKU>aSKU</SKU> tags are defined in all your listings.
However; GetSellerList API returns multiple Items that match to a single SKU if they were all listed as such:
1. <InventoryTrackingMethod>SKU</InventoryTrackingMethod> tag is NOT found in those items
2. <SKU> tag was defined with the same value for the listings
