    <description>&lt;P&gt;&lt;STRONG&gt;Direct Answer&lt;BR /&gt;&lt;/STRONG&gt;&lt;BR /&gt;Yes, ArcGIS Pro geodatabase topology does NOT support multipoint feature classes. When you try to add a multipoint feature class to a topology, you will get an error:&lt;/P&gt;&lt;P&gt;&lt;EM&gt;“The geometry type (MultiPoint) of the feature class is invalid for participation in a topology.”&lt;/EM&gt;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;&lt;STRONG&gt;Why is this the case?&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;Geodatabase topology in ArcGIS Pro is designed to enforce spatial integrity rules among point, line, and polygon feature classes.&lt;BR /&gt;Multipoint geometry is treated differently because topology rules rely on relationships like shared edges or coincident points, which do not apply well to multipoint collections.&lt;BR /&gt;&lt;BR /&gt;&lt;A href="https://pro.arcgis.com/en/pro-app/latest/help/data/topologies/topology-in-arcgis.htm" target="_blank"&gt;Topology in ArcGIS—ArcGIS Pro | Documentation&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;&lt;STRONG&gt;Supported Geometry Types&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;Point&lt;BR /&gt;Polyline&lt;BR /&gt;Polygon&lt;BR /&gt;These can participate in topology and have associated rules (e.g., Must Not Overlap, Must Not Have Gaps, Must Be Covered By).&lt;BR /&gt;&lt;BR /&gt;&lt;A href="https://pro.arcgis.com/en/pro-app/latest/help/editing/geodatabase-topology-rules-for-point-features.htm" target="_blank"&gt;Geodatabase topology rules and fixes for point features—ArcGIS Pro | Documentation&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;&lt;STRONG&gt;Workarounds&lt;BR /&gt;&lt;/STRONG&gt;&lt;BR /&gt;If you need topology-like validation for multipoint data:&lt;/P&gt;&lt;P&gt;Convert multipoint to single-point features using tools like &lt;STRONG&gt;Multipart To Singlepart&lt;/STRONG&gt; or &lt;STRONG&gt;Feature To Point&lt;/STRONG&gt; before adding them to a topology.&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;Alternatively, use attribute rules or custom scripts for integrity checks on multipoint datasets.&lt;/P&gt;</description>

      <description>&lt;P&gt;When i try to add feature class to participate in topology. I was getting an error "The geometry type (MultiPoint) of the feature class is invalid for participation in a topology". is there a way to support or work around for this?&lt;/P&gt;</description>
