The last time I needed to update the Marketing Channel Processing Rules for multiple RSs the template feature worked fine; this was several weeks ago.
Today it is broken.
I can select all RSs, select my template, but when I save the change to the 220 selected RSs, the product changes to state that the change was make to only 1 RS.
This is a real pain and ClientCare's solution of manually changing each RS separately isn't viable.
Since this is an older post, I'm sure these bugs have been resolved in future releases. If you continue to experience bugs, please report them to Customer Care
Ahh... my ticket on this is only a week + old. Boy, they made me do a ton of process documentation before they logged the ticket though. Would've been nice if they'd checked for an existing ticket before making me jump through hoops.
I submitted a ticket on this 5+ weeks ago and am still awaiting a fix.
