Attribute Rule to Update a Field based on edit to another Field

Anonymous User — Fri, 23 Apr 2021 20:28:49 GMT

Hello,

I am new to arcade expressions and I am attempting to make a new attribute rule for a Stream polyline feature class. My goal is to track when a features name has changed. Where, if the Stream Name field (Str_Name) is updated, then another field (NameChange) within the same feature class table is updated to say Yes.

I have looked at some other resources and think that I am close, but I keep getting "False" instead of Yes or No.

Here is a snip of the attribute rule. I am using an Immediate Calculation Rule.

Any help would be appreciated.

Thanks!

Are you basing your expression on this post from @HusseinNasser2 ?

I was. I have since figured it out after messing around. Using some logic and Return and a string.

Thanks!

Simple and elegant! I've never had occasion to use the $orginalfeature global, but it looks like it can be very helpful.
