The Level element is a complex type that defines a single level in a hierarchy

Elements and Attributes

The following table lists the elements and attributes that define the Level element.

Name	Is Required	Description
Source	Yes	A container for the property reference.
PropertyRef	Yes	A reference to an instance property. Other attributes of the level, such as captions, name, and reference name, can be taken from the referenced instance property. If so, you do not need to specify these in the Level element.

Remarks

Example Tabular

The following example, in CSDLBI version 1.1, shows the definition of multiple levels in a hierarchy from the AdventureWorks tabular model sample.

  
<bi:Hierarchy Name="Category">  
   <bi:Level Name="CategoryName">  
     <bi:Source>  
       <bi:PropertyRef Name="CategoryName" />  
     </bi:Source>  
   </bi:Level>  
   <bi:Level Name="ProductName">  
     <bi:Source>  
       <bi:PropertyRef Name="ProductName" />  
     </bi:Source>  
   </bi:Level>  
</bi:Hierarchy>  

Example Multidimensional

The following example, in CSDLBI version 1.1, shows a hierarchy with multiple levels, from the Contoso Operations cube.

<bi:Hierarchy

   ReferenceName="Product Hierarchy">  
     <bi:Documentation>  
        <bi:Summary>DESCRIPTION_ProductModelCateg_Hierarchies</bi:Summary>  
     </bi:Documentation>

        <bi:Source>  
        <bi:PropertyRef Name="ProductLine" />  
        </bi:Source>  
     </bi:Level>

        <bi:Source>  
        <bi:PropertyRef Name="ModelName" />
