"cannot make changes while change set %s is advancing"
*Cause: The change set is currently advancing. Change sources related
to an advancing change set cannot be altered. Change tables
related to the advancing change set cannot be created, altered
or dropped. Some or all the parameters of the change set cannot
be altered while the set is advancing.
*Action: Wait until the change set has finished advancing, then reissue
the command. If altering the change set, only the advance_enable
parameter can be altered during an advance.
