QueryContactIN - Unexpected results ?!

[MarkTotnes]

Hi Community,

I am running what looks to be a simple query to return Contact Info FOR A SINGLE Contact by looking up via email address.

The POST I am using is:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ContactByElementsQuery_sync xmlns="http://sap.com/xi/SAPGlobal20/Global">
<ContactSelectionByElements>
<SelectionByWorkplaceEmailURI>
<InclusionExclusionCode>I</InclusionExclusionCode>
<IntervalBoundaryTypeCode>1</IntervalBoundaryTypeCode>
<LowerBoundaryName>info@redacted.com</LowerBoundaryName>
</SelectionByWorkplaceEmailURI>
</ContactSelectionByElements>
<ProcessingConditions>
<QueryHitsMaximumNumberValue>1</QueryHitsMaximumNumberValue>
<QueryHitsUnlimitedIndicator>false</QueryHitsUnlimitedIndicator>
</ProcessingConditions>
</ContactByElementsQuery_sync>
</soap:Body>
</soap:Envelope>

.... HOWEVER (!), I am getting what looks like a huge list (maybe all our contacts) of contacts, regardless of their email address ?

Would anybody know why the above is not just returning the single contact that has email address 'info@redacted.com' ?

Thanks in advance,

Mark
