Deleting attachments on branch versioned data

[AmyRoust]

I'm setting up a process to download attachments from several feature classes before deleting them from the database. The feature class and the attachments table are branch versioned. As near as I can tell, there is no way for me to batch delete attachments, either with the Remove Attachments tool or the Delete Rows tool. Am I missing something? I tried publishing a service with the attachments table in it, but it doesn't appear in the service.

Confirmed with Esri Support that this workflow is not currently supported. Esri case 03897472. Case summary from the tech:

"To summarize our discussion/workflow:

• We have a trace network in our Enterprise geodatabase, from which we are publishing a feature class along with its attachment table to ArcGIS Enterprise as a feature service
• On checking the feature service from Portal, the feature layer is present however, the attachment table is not visible
• The attachment table is visible on the map image layer
• Tried publishing from a new ArcGIS Pro project with a new database connection, however, got the same results
• Got the same results with different data
• Opened the feature layer in Portal map viewer > configured pop-ups > the attachments were visible > we could also edit the attachments
• Our main goal is to utilize the attachment table from the feature service in model builder in ArcGIS Pro

I tested the workflow in-house and was able to reproduce the results. What we are encountering is expected and is a limitation. I also reached out to a colleague of mine regarding the model in ArcGIS Pro. Unfortunately, we currently do not have a workaround to this and agreed that the best way to move forward would be the one you mentioned over the call."
