Updating coded domains on portal

LLCCG

I'm a new GIS tech (and only GIS tech) at an organization. This organization has a map layer that has coded domains for a field. The engineering team asked if we could add another value. I added it to the layer in ArcGIS Pro (2.7).

That layer is visible through Portal. If I make a change to a feature on the desktop, that change is immediately visible on the webmap.

However, my new coded domains are not updated. If I change the value of a feature on the desktop, the new value shows up on Portal (that is, if I manually change something from "0" to "1", it will show "1" when I click on it in the webmap). However, if I try to edit it in the webmap, the new value isn't an option. If I go to the layer's description in Portal, it only shows the old coded domains, and not the new ones that I added in Pro.

How do I get these to update?

OK, that makes sense. This is a map service with feature access enabled. Since this isn't hosted you'd have to update the domains in the service by either overwriting the service by republishing or using the REST API (to update the service definition.

I would try and find out who published it and how. You can also check the service details in ArcGIS Server Manager and to see the original document used to create it and try and find that. Re-using that same document is the easiest way to republish. Make sure you pay attention to the Layer IDs, if those change it will break any Web Maps using the service.

Check the request in dev tools and see what the error is, it will be an updateDefinition call.

I just tried to add a value to a domain on our 10.9.1 box and I received an error.

I tried again with the browser dev tools open and looked at the response of the request and it had an error that the description was not a string (it was null in the request).

So I added a description to the field, then tried modifying the domain again and it worked fine.

Were you able to resolve this issue? I am getting the same error when I try to add domain values at 10.9.1.

Hi,

You may have more success editing the domain list via JSON from the REST endpoint as explained in this article:

How To: Add coded value domains to a hosted feature service from a REST endpoint (esri.com)

Just be sure to do it during downtime and save a json of the unedited service before you do so.

I've since transitioned my organization away from an Enterprise and Portal deployment to totally hosting in ArcGIS Online, which allows easier updates to the Domain values than what I had to content with in Enterprise - but I remember using the REST endpoint to edit coded domain values succesfully. Worked sometimes, didn't work others.

Hello Henry,

I am following your exact steps. We just upgraded to 10.9.1 and when I try to delete or add an item in the domain I get "there was an error" with no other information. I have tried it several times with no luck. Any other ideas?

Thank you,

I was, but all it took was republishing.

Hello, were you able to find the solution to your issue? I'm having a similar one right now, though I've done this dozens of times before. I have a feature layer published from a geodatabase to the federated server we have set up with our org's Portal. I added a value to a coded domain in ArcCatalog, republished the service and... nothing. Sometimes I find it helps if I create a feature in a desktop program that already has the new coded value in it before overwriting my feature service, but that isn't working this time either. I don't know why I'm running into brick walls right now when I've done this process before, but if you found a solution I'd love to hear what you did!

LLCCG

I think I'm both.

You probably have to be the Item owner or an administrator.

Is there any reason that I wouldn't have an "Edit" button?

Hi LLCCG, can you confirm if you're attempting to modify the Domains of a live Feature Service or Hosted Feature Service? I assume that's what you're trying to do.

If that's the case, this can be tricky, and I struggled with it quite a bit when I was starting out with GIS at my organization. I'm assuming you're using Portal for Enterprise and attempting to modify a live Feature Service but I think this strategy works for Online as well. Prior to changing anything with the service I advise you to save/export a backup of the original service in case something goes wrong. And if you can make these changes during down hours when nobody is using or working with the service that is the safest option.

The easiest method I've found is to:

1) Navigate to the feature layer in your Portal's Content.

2) Select the Data tab on the blue bar for the Portal item.

3) Select the "Fields" button next to the "Table" tab to show the list of fields for the service.

4) Find the field that you want to change and click it's Display Name.

5) You will then see an overview of the Field and its details, including a List of Values (Domain)

6) Next to the List of Values (Domain) click edit. You should now be able to Add a new Domain Code and Label.

7) After that is done click Save at the bottom. For me, the Save sometimes returned a fail message and it took another try or two in order for the new domain code to stick.

Hope this helps, but as I said before be very careful when changing the data's schema. Save/export a backup of the original service in case something goes horribly wrong and you need to republish it later. There's another method that involves editing the layer's JSON through Portal Admin - but try it through the Portal first if you can.
