Distrubution & Assessment cycles - CO

Hi,

I seem to be having problems when executing the cycles. The sender is correct but there seems to be no receiver. The error message I got was "The segment contains no receivers"-GA733. Could it be because the version that I'm using is different than the documentation provided? If so how do I change the indicators in "Partner object update" table? Or what else do I do as I've tried every possible solutions given and the only thing that is changing is the number of messages. The number of senders is correct but only number of receivers is shown 0. Please help.
