How do you identify multiple services from a single data source

[JeffSilberberg]

With the announcement of a June 24th update that enforces a "Restriction on publishing multiple services from a single data source", I would like to know how I can identify in advance any issues in my organization's instance.  

ArcGIS Online Will Update Soon

This email is to notify you that we plan to update ArcGIS Online on June 24, 2026, from 5:00 p.m. to 12:00 a.m. (PT). ArcGIS Online updates are applied automatically with no expected downtime.

If you're referring to services that are not hosted feature layers, but services you published from a enterprise portal or non-federated server, you can go to the server manager and look at the services in detail there. There's an option listed right next to the service name, it looks like a small database icon. Click that, it'll list the details of where the service is coming from.

Hope this helps!

   I am not really sure what I am referring to. 

I received the Email notice on the update, and the fact that the "feature" was not going to be supported as of the update.  But I honestly an not sure how to identify if any of the many "authors" have used this and what the impact would be on the organization.  

"Restriction on publishing multiple services from a single data source

Prior to this update, organizations could publish multiple supported services from a single eligible source data item, creating a one-to-many relationship between source items and published services. To align with existing publishing restrictions, ArcGIS Online will now enforce a one-to-one relationship between supported source data items and published services. With this change, only one service can be published from each eligible source data item type. Hosted Feature Services are not impacted by this change and will continue to support the creation of multiple child items, such as Tile Layers and OGC layers. Organizations that currently publish multiple services from the same source item will need to create copies of the source data item to continue creating additional services."

Weird. That would likely break a lot of services out there if that happens. I haven't seen any emails from Esri regarding it but I'm not a part of the early adopters/beta tester thing for ArcGIS Online. 

Thanks for the heads up though! I'll be curious what happens from this.

I'm glad I'm not the only one confused about this. If it means you can't publish multiple services from one Enterprise Geodatabase feature class, wouldn't that like, completely defeat the purpose of that entire products?

Here's a copy of the full email, for those of you who did not receive one:Early Morning Email of May 22, 2026, from ESRI.

I'm in the same boat as OP, regarding what that first paragraph really means...

What exactly is this "single eligible source data item" to which ESRI is referring?

All they explain is that it isn't "Hosted Feature Services."

Would be really nice to get some clarity of what is affected, rather than the only example being what's not affected.

[ZachBodenner]

Agreed, and the other thing that's interesting is that this is an AGOL change, not an Enterprise one. So it's not like you could publish a referenced enterprise geodatabase dataset to AGOL anyway (at least not without your own server as an in-between). So I also don't really know what this is referring to. Now, Enterprise of course receives all the code changes to AGOL eventually, so I think this does really need to be clarified.

I know we should not reference politics in the forums, for the sake of professionalism and basic dignity, but I suddenly had a flashback to then-PM Teressa May's "explanations."

Public: "What does Brexit mean for us?"
Teressa May: "Brexit means Brexit!"
Public: "Oh, okay... But what should we expect?"
Teressa May: "Don't worry! It won't be as bad as Mad Max!"

We also got this email today. And I am totally confused. We have a lot of services that use the same feature classes and hence data sources. Our parcel feature class is used at least in 6 various services. These services are being used in various applications and integrations with Lucity and Accela. How will it affect us?
