Attribute Rule - Generate ID

RMR — Fri, 25 Aug 2023 08:22:35 GMT

In the old Desktop Attribute Assistant, you could create multiple rules:

Create a rule to generate incremental sequential IDs (Max + 1) based on the last generated ID (the generated ID starts at 1000).
Copies a series of values from the nearest feature in a specified layer.

In the screenshot, you can see how the rules are defined in ArcMap/Attribute Assistant. I've tried several codes in Attribute Rule without success. How can I achieve these actions in ArcGIS Pro?"

For the IDs, see my answer in this question: https://community.esri.com/t5/arcgis-pro-questions/using-attribute-rules-to-create-sequential-id/m-p/1320130

For returning the nearest feature's attributes, you could do something like this:

// Calculation Attribute Rule // field: empty! // triggers: Insert, update var other_fc = FeaturesetByName($datastore, "Etages") var search_dist = 1000 // get all features in other_fc within search distance var other_near = Intersects(other_fc, Buffer($feature, search_dist)) // find the nearest var min_dist = search_distance var other_nearest = null for(var f in other_near) { var dist = Distance($feature, f) if(dist < min_dist) { other_nearest = f min_dist = dist } } // abort if no feature was found in the search distance if(other_nearest == null) { return } // copy the attributes return { attributes: { EtaID: EtaID, EtaCode: EtaCode, NivCode: NivCode, } }

Hello, I would like to thank you for responding to my request so quickly and for the solution provided. I have encountered an issue with this code on my map, as it doesn't seem to recognize the "Etages" layer. Could you please let me know the possible reason for this?

Attribute Rules don't work with layers in maps, they work with featureclasses/tables in the same database.

Etages has to be in the same database as the fc where you are implementing the rule
If the name is different, change it in the expression
If you are working in an Enterprise database (.sde), change the name to the full name: DatabaseName.DataOwner.TableName
