Attribute Domain

I have a problem. I created a range domain and defined the <Sum Values or Area Weighted>in the merge policy. After that, when I merge two features, the result is not the sum of the two features. It takes one of the values from the source features.

I think this functionality is broken in ArcPro, I made the same question in September last year here and no one from ESRI has stepped up to say why. May be I have done something stupid, but your workflow is identical so makes me think it's broken? Would be good to get some clarification from ESRI!

@MohamedIsmael , @DuncanHornby Domain merge policy is not currently supported for the Merge editing tool(also documented here). However, the expectation you have documented is reasonable. I also wanted to mention that this is on our radar for consideration. Thanks.

You are welcome to enter this as an idea for others to upvote.

@JMutunga I had searched high and low the help file for any advice on the merge policy. I have to say 1 line tucked away on the tool is a bit obscure! And its not even emphasised by say the grey box that the documentation uses. I had crashed around the help file on the pages that document domains and these polices. That's where I had been searching for any advice. I would recommend you get your help documentation team to replicate that 1 line (I'm sure they can find the time to do that) and state within the domains policy section here that it does not actually apply to the Merge edit tool.

With that said it has been good to get some clarification and I had not been doing something wrong with setting up a merge policy on a domain. This useful discussion leads me to one final question, when does the merge policy get execute, does it only run when using the merge or dissolve geoprocessing tools for example?

@DuncanHornby Your feedback is noted about improving our Help. Thanks.

The simple answer about your question is that there is no tool in ArcGIS Pro that honors merge policies at the moment. The use case(s) highlighted on this thread are solid and there are others relevant to Utility Network users that the development team is actively monitoring as guide to prioritization and eventual implementation.

I hope this helps.

FWIW (For What It's Worth)

If you use the parcel fabric, every parcels has a 'Stated Area' field and a 'Stated Area Unit' field. When you merge parcels together:

The areas are summed taking into account the different area units of the source parcels. The result will be reflected using the default area units of the project.
you can see the summed area in the merge pane before pressing merge.
The merged parcels become historic (they are not deleted)

Q. Can a 'parcel' be used for buildings or units within a building?

A. Yes - many customers use the parcel fabric to model their condominium units, which is a type of conveyance division. We call those 'strata parcels' and can make them 'floor aware'.

The Merge workflow is documented: https://pro.arcgis.com/en/pro-app/latest/help/data/parcel-editing/mergeparcelsworkflow.htm
