Anyone else found this?
I'm using 10.2.0.
I have 2 GP tools that both reference project data on a UNC share. ArcGIS Server has a registered Data Store (folder) pointing to the same location.
I can publish either tool individually and it successfully publishes without copying data to the server (expected behaviour).
However, if, while publishing one, I click "Add Result" in order to pull the second tool into the same service, then now when I publish, all project data gets copied to the server.
Is this expected behaviour?
