Auto initiation of discussion when change request moves from new state

[Ssinha4]

An auto discussion is initiated for change request when for normal change state moves from new to access and for standard from new to scheduled. Is this an OOB behavior? if yes, then how to disable this.

We've been experiencing the same behavior since the Yokohama upgrade and haven't yet been able to determine why the sidebar discussions are being created automatically.

There is a business rule, but we have it inactive:
"New sidebar discussion created"

This contains an incident (not like in our discussion creation a change) and calls a subflow that isn't triggered otherwise. I haven't been able to find any other place in the system so far.

If anyone has a solution, please let me know.

Best regards,
Oliver
