Attribute Rule not saving in ArcGIS Pro when the feature class is in WGS 1984 Web Mercator (auxiliary sphere)

AbiDhakal

Hello GIS friends,

I'm trying to save an Attribute Rule in a polygon feature class with WGS 1984 Web Mercator (auxiliary sphere) projection and it is not saving. However, when I put the same Attribute Rule for a feature class in NAD 1983 UTM Zone 16N projection it gets saved.

This is what I'm putting. round(Area($feature, 'acres'),1)

Thank you for your help.
Abi

If it's red, mouse over it to see what the error is.

Ohhhh the other thing that I forgot: The feature class must have GlobalIDs enabled. That's bitten me several times.

Weird. Does it change if you use AreaGeoDetic() instead?

@AlfredBaldenweck - When I put

AreaGeodetic(Geometry($feature), 'acres')

for a feature class in WGS 1984 Web Mercator (auxiliary sphere) projection it does not save. It verifies the expression to be correct, but it does not save. Also, when I put that expression for a feature class in NAD 1983 UTM Zone 16N projection it verifies it wrong.

AlfredBaldenweck

If by verifies it wrong, you mean it returns a different value, that's expected. Area and Area Geodetic measure differently.

Testing it out myself, I also get that error for the NAD83, so that's fine.

I'm testing in a file geodatabase in Pro 3.1.3, and it's working for me

Make sure you have the following if it's just a problem literally saving the rule:

Rule Name
Description
Field
Expression
Triggers

I frequently can't save because I forget the description.

AbiDhakal

I have these and I'm still not able to save.

1. Rule Name (Get Area)
2. Description (Get area)
3. Field (GISAcres)
4. Expression: AreaGeodetic(Geometry($feature), 'acres')
5. Triggers (Insert, Update)

Thank you for trying to help me.

And the bite took a chunk out of me; it's been very painful so hopefully I will not forget this one. Thank you! That did it!
