FetchXML View to include attributes from a nested object link

I would like to have a view showing the attributes of three objects:
Statistics has a search by Account and Account for search.
The view is related to statistics, and I need attributes from all three objects; is it even possible?

Problem with GridXML.
I want to include the wl_city attribute in GridXML.

This is FetchXML with related objects:

<fetchxml>
  <fetch version="1.0" output-format="xml-platform" mapping="logical">
    <entity name="sb_statistics">
      <order attribute="sb_amount" descending="false" />
      <!-- It is easy to get these into the GridXML -->
      <attribute name="sb_debtor" />
      <attribute name="sb_date" />
      <attribute name="sb_amount" />
      <link-entity name="account" from="accountid" to="sb_debtor" 
       alias="relatedAccount" link-type="outer">
        <!-- It is possible to get this into the GridXML
             by using the link-entity alias: relatedAccount.wl_towncity -->
        <attribute name="wl_towncity" />
        <link-entity name="wl_postalcode" from="wl_postalcodeid" 
          to="wl_postaltowncity" alias="relatedAddress" link-type="outer">
          <!-- I have trouble getting this attribute into the GridXML -->
          <attribute name="wl_city" />
        </link-entity>
      </link-entity>
      <attribute name="sb_statisticsid" />
    </entity>
  </fetch>
</fetchxml>

When I modify GridXML as shown below, this error appears when I open the view:
"To use this saved query, you must delete the criteria and columns related to deleted or non-searchable items"

  <layoutxml>
    <grid name="resultset" object="10008" jump="sb_name" select="1" preview="1" 
     icon="1">
      <row name="result" id="sb_statisticsid" multiobjectidfield="1">
        <cell name="sb_amount" width="100" />
        <cell name="sb_date" width="100" />
        <cell name="sb_debtor" width="100" />
        <cell name="relatedAccount.relatedAddress.wl_city" width="100" />
      </row>
    </grid>

The third thing you should know is that when you return the nested result, the type is an object, but the original type AliasedValue, so you must first pass the object to AliasedValue. then he will be ready to pass it on OptionSetValue. after that you should look for .Valuewhich has the result of what you want
