Not able to fetch “Name” of lookup fields of Link-Entity (Web API + FetchXml) RRS feed

  • Question

  • I have some fetchXml that I am executing through the Dynamics CRM Web API. THe fetchXml query is constructed like so:

    <fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
      <entity name="new_someEntityA">
        <attribute name="new_lookupForSomeEntityA" />
      <link-entity alias="new_someEntityB" name="new_someEntityB" from="entityBId" to="entityAId" visible="false" link-type="outer">
        <attribute name="new_lookupForSomeEntityB" />

    When I send this query through the Web API, I get a response and the value for "new_lookupForSomeEntityA" includes the value (GUID) and a Formatted Value (it's name). But the response for "new_lookupForSomeEntityB" includes just the GUID and I can't find a way to get it's GUID and value. I've added a header record for:

    "Prefer": "odata.include-annotations=OData.Community.Display.V1.FormattedValue"

    but that appears to just get me formatted values for the primary entity and not the link entity. Is this a limitation of the Web API or am I doing something wrong? Any help would be appreciated.

  • Is this a 1:N relationship from A -> B ?  So A would be like the account entity, and B would be like Contact?

  • It's a N:1 relationship from A -> B.

  • You need to use alias with the attribute which you want to retrieve from linked entity.
