"Copy File" Tasks created on the Child SMP are replicating up to the Parent SMP.
Known issue. Seems to be the dependency on the software package, that implemented for the task "CopyFile" in the previous release is the reason for the task replication up the hierarchy.
Packages are replicating up since CopyFileTask resources that are created for this task are plain SoftwareComponentResource(s). So they are replicated unconditionally up by "Software Resource Summary" Relocation rule. It just takes all resources of SoftwareComponentResource type and replicates them up ignoring any replication direction settings. The same story is with Image resources.
ITMS 8.5 RU3, RU4
This issue has been reported to our Symantec Development team. A fix is planned for our next release: ITMS 8.6
