AddItem API request is blocked  if the Item.LotSize is set to 1 as below in the request :

<LotSize>1</LotSize> <Quantity>5</Quantity>

 However why the following setting is allowed via SYI flow?

Number of lotsImage
Items per lotImage

Summary 

  By definition, a lot is a set of two or more similar items that must be purchased together in a single transaction. This rule applies to both AddItem API and SYI flow that the Item.LotSize property can't be set to 1 through either AddItem API call or SYI flow. As a result, when the value of the Items per lot is set to 1 in SYI page as below the listing is programmtically determined as a 'non-Lot'  item  and any "Lot" associated properties are removed from the listing.

        B.  specify the property in AddItem API request

              <Quantity>5</Quantity><LotSize>1</LotSize>

    Result : the AddItem call is blocked as expected :

<?xml version="1.0" encoding="utf-8"?>
<AddItemResponse xmlns="urn:ebay:apis:eBLBaseComponents">
  <Timestamp>2008-01-28T19:07:18.187Z</Timestamp>
  <Ack>Failure</Ack>
  <Errors>
    <ShortMessage>Lot Size is invalid.</ShortMessage>
    <LongMessage>Lot Size is invalid, need to be greater than 1, and less than 10000.</LongMessage>
    <ErrorCode>17000</ErrorCode>
    <SeverityCode>Error</SeverityCode>

  </Errors>
  <Version>549</Version>
  <Build>e549_core_Bundled_5967386_R1</Build>
</AddItemResponse>

   Workaround / Recommendations for the Use Case 2.B

  When the value of the Item per lot is set to 1 in your Listing  tool,  remove the <LotSize> tag or property from the AddItem request in question.
