https://community.esri.com/t5/arcgis-pro-questions/field-calculation-many-to-one-from-another-layer/m-p/1324072#M72622 <P>I will try to explain this as best as I can. I have two feature classes. Feature class 1 (fc1) is a layer that consists of buffers that represent shoreland districts with a bunch of overlapping polygons (indicating overlapping shoreland districts). Using the Union tool, I split out all these overlapping sections so each polygon was split along the overlap. Feature class 2 (fc2) merges all of the identical overlapping polygons into one feature. The images below show the polygons with a transparent fill to show the overlapping polygons (fc1) and the merged polygons (fc2). Feature class 1 has a field that indicates which shoreland district each polygon represents.</P><P>fc1:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MelissaGearman_0-1693424202080.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/79496i98496E8A7B9AD6E8/image-size/medium?v=v2&amp;px=400" role="button" title="MelissaGearman_0-1693424202080.png" alt="MelissaGearman_0-1693424202080.png" /></span></P><P>&nbsp;</P><P>fc2:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MelissaGearman_1-1693424247299.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/79497i6C0A8FFC4F808BC8/image-size/medium?v=v2&amp;px=400" role="button" title="MelissaGearman_1-1693424247299.png" alt="MelissaGearman_1-1693424247299.png" /></span></P><P>&nbsp;</P><P>What I need to do is populate a shoreland district field in the fc2 layer that represents all the shoreland districts that are part of that polygon.
