I am trying to publish a Feature Access service from our enterprise geodatabase to portal with the ability to take attachments. I am publishing from ArcGIS Desktop to our service servers and then using this in our portal. Arc flags an error when trying to publish this service with Sync enabled because the relationship is based on OBJECTID. Basically I want to allow users to new points as well as the ability to add an attachment. Any help?
So got it working. I added global IDs to my original feature class and when I enabled attachments it used this instead of the OID. I think this fixed it. I think I was checking the sync box which I think was fouling it up too.
Now to figure out why editor tracking isn't working.
