I am using ArcGIS Enterprise 10.7.1 (Portal) and I have a Hosted Feature Layer View that has a Layer and a few related Tables. I wish to enabled the Editor Settings so that Editors can only Add features. The attachments are being stored in one of the related Tables. Users are submitting new records to this Hosted Feature Layer View via Survey123.
When a user submits a record via Survey123 with the Editor settings as Add Only, the Attachment they include is not coming through. The form acts like it submitted OK, but the Attachment is not actually attached.
If I change the Editor settings to Add and Update features, the Attachment comes through OK and is in fact attached.
If I had to guess, I would say the record is getting created first and then the Attachment posted to it after as an "Update" and since this is not allowed under Editor settings of only Add features, the attachment does not post.
Is there another way I should be configuring my Editor settings or is this a bug?
Any help would be greatly appreciated. Thanks!
