Changing Collector for One BU Also Updates Collector Assignments for Other BUs

Summary:

Hi Team,

We’ve noticed unexpected behaviour in Oracle Fusion Collections when using the Manage Resources screen. When we reassign a collector for only one BU (from Collector A to Collector B), the system also moves Collector A’s other BU assignments to Collector B. Our intention was to change the assignment for just a single BU, but it appears that all BU assignments are being updated.

Could someone please confirm whether this is the expected behaviour?
If not, is there a specific setup or configuration we should review to ensure collector assignments remain BU‑specific?

Any guidance would be appreciated.
