Attribute rule to change domain value based on date

PetronellaHauptmann1 — Wed, 23 Mar 2022 08:30:00 GMT

Hi everyone.

I'm trying to create an attribute rule that changes a domain value when a specific date is passed.

So the main problem I'm trying to solve is this:
When a feature is created, the feature gets domain code 105. When the feature is up for review in a process, the administrator changes the domain code from 105 to a value between 100-104 and sets a end date in another field. When the end date is passed I want the domain code to change back to 105.

Here is the Arcade-code I've been working on. It validates just fine, but when I execute the rule the domain value does not change.

var skedenr = $feature.Skede
var utstallningsdatum = $feature.Utstallningsdatum
var dagensdatum = Today()
var skede = IIF(skedenr != 105, '1', '3')
var datum = DateDiff(utstallningsdatum, dagensdatum)
var datums = IIF(datum <= 0, '1', '3')
var sant = IIF(skede + datums == 2, 105, skedenr)
return sant

Super grateful for help!

It sounds as if you want the field to update itself when the specified date is passed. That is not possible. An Attribute Rule only triggers when you actively do something to a feature (insert/update/delete), they are not checked continually.

What you can do is create a Batch Attribute Rule. These are rules that don't trigger on insert/update/delete, but are evaluated when the user wants.

Batch rules need Editor Tracking, so enable that for your feature class.
Enable or disable editor tracking—ArcGIS Pro | Documentation
Create a new Batch Calculation Attribute Rule
- This will add a new field "VALIDATIONSTATUS" to your table.
Use your script or the script below (slightly modified)
Evaluate the rule periodically
- Use the tool Evaluate Rules (Data Management)—ArcGIS Pro | Documentation
- Either do that manually or write a Python script and run that automatically every night

var skedenr = $feature.IntegerField var utstallningsdatum = $feature.DateField if(skedenr == null || skedenr == 105) { return 105 } if(utstallningsdatum == null) { return skedenr } var datum = DateDiff(utstallningsdatum, Today()) return IIF(datum <= 0, 105, skedenr)

My test features before and after evaluating the rule (on 2022-03-24)

Before	After

Notes:

The second row didn't get changed because there was no date supplied.
The last row didn't get changed because DateDiff(datevalue, Today()) returned 1 hour. Might be related to daylight saving time, I don't know. This is a file gdb, did not test on enterprise.
- To change this behavior, you can replace the last 2 lines with this:

var datum = DateDiff(utstallningsdatum, Today(), "hours") return IIF(datum <= 1, 105, skedenr)

It works just fine.

I am so grateful for your help!
