FetchXML Notes

Link Entities

When retrieving attributes from linked entities it seems that attributes must have an alias otherwise you can't refer to them:

<fetch distinct='false' mapping='logical' aggregate='false'>
<entity name='productpricelevel'>
<attribute name='amount'/>
<attribute name='transactioncurrencyid'/>
<link-entity name='product' from='productid' to='productid'>
<attribute name='transactioncurrencyid' alias='producttransactioncurrencyid'/>
<attribute name='price' alias='price'/>
<attribute name='productid' alias='productid'/>
</link-entity>
</entity></fetch>

Updating FetchXML Reports

According to this article, http://www.magnetismsolutions.com/blog/paulnieuwelaar/2011/12/18/Run_Fetch_XML_Report_on_Selected_Record_in_Dynamics_CRM_2011.aspx you should not upload an .rdl file into an existing report because the context in which the report is run is not changed.
