Calculate Field with Multiple Entries Based on One Object ID (Concatenate?)

KevinTate — Mon, 29 Mar 2021 15:05:11 GMT

Hello!

I am creating a layer for a non-profit that identifies priority watersheds based on our many partners' involvement. I have used the "Count Overlapping Features" tool to create a layer which displays the frequency in which a partner has identified a specific HUC12 watershed as a priority.

The table I have below displays our partner names by Overlap ID in separate entries. For example, Overlap ID 441 has CBF, FOSR, NRCS, and SWCD displayed as 4 separate rows/entries. I want to display these 4 partner names in one field linked to the Overlap ID. "Overlap ID" 441 would have a "Partner Overlap" Field that would display the text "CBF, FOSR, NRCS, SWCD". This would allow the viewer of the attribute table to easily see which organizations were involved in a certain HUC12 watershed.

I've gotten close with Concatenate in the field calculator, but cannot figure out how to limit to multiple entries of one singular field.

Thanks for your help!

Upon further inspection I am NOT looking to simply concatenate. What I'm looking to do is group based on a single object ID field, then show all entries associated with that field in a single cell. Turning 4 entries into 1 with concatenated values.

I looked through the above linked threads and I saw a few other people with my same issue, but no answer. I saw a python script to make a tool to do this automatically, but no directions on how to implement. Is there a python code that I can plug into field calculator to create the product I'm looking for?

No. There is no code that can accomplish this within the Field Calculator tool, which is why @DanPatterson created a tool for it in Free Tools for ArcGIS Pro: Table Tools - Esri Community .
