Coded Value Domain: Assign multiple codes to a single description

ClintSteeves1 — Thu, 10 Apr 2025 15:43:22 GMT

Does anyone know of a more efficient way to set up a coded value domain where numerous code values can represent a single description? Here's a snippet to show what I have:

What I'd like to see is something along the lines of:

Code	Description
0-2	Low Risk
3-5	Medium Risk
6-8	High Risk

Code	Description
0, 1, 2	Low Risk
3, 4, 5	Medium Risk
6, 7, 8	High Risk

The number that will be used to determine risk level is calculated from four other numerical fields, and although I recognize I could set up the script to assign values of 0, 1, or 2 based on those number ranges, it would be nice to not require a workaround like that. I'd like to maintain the actual calculated values, because a High Risk with level 6 is still of lower importance than a High Risk of level 8.

Obviously, this is working as-is, but I was just wondering if anyone had any suggestions for a situation like this where perhaps the code values can range from 0 to 100. Inputting a description for each one of those code values would be a tedious job, even using a script.

Thanks

If you make good use of the script tool parameter types this can be an efficient script tool. I've attached a tool with no code to execute but the parameters and validation already done, this illustrates how you can quickly gather a bunch of code ranges and their associated descriptions, for both new and existing domains.

I'll check that out, thanks

So I'm thinking a calculation attribute rule would be possible in this scenario. The arcade code block in building the attribute rule would be something like this:

var code = $feature.Code;
var description = When(
code == 0 || code == 1 || code == 2, "Low Risk",
code == 3 || code == 4 || code == 5, "Medium Risk",
code == 6 || code == 7 || code == 8, "High Risk",
"Other"
);
return description;

You can make it an immediate calculation rule so when an editor types in the value 1 for the code field, the attribute rule triggers and calculates the Description field to be "low risk". Caveat here - I'm not an arcade guru so the script may need some tweaking.

This stores the code in one field and the description in another, which is different from having a coded-value domain on an integer field. Not strictly wrong, but not as useful as a proper field in my experience.

True. Just another way of looking at the question I suppose.
