I'm afraid you can't. You can read the status manager value through
the Statusing Service (
http://msdn.microsoft.com/en-us/library/
websvcstatusing.statusingdataset.assignmentsrow.wres_uid_manager(office.
12).aspx), but you can't change it. The supported project fields for
updating through the Statusing Service (
http://msdn.microsoft.com/en-
us/library/bb428845.aspx) do NOT include status manager.
Practically this means that you can't approve timesheets (timephased
data) through the PSI, if the status manager is different from the
user you are running your program.
