Thanks a lot Thomas Chan. The version is Update10 and the platform build version is 7.0.4641.16233.
But i think by allowing to Soft Assign, Hard assign (which can be ONLY done from the screen in WBS) and Soft Book and Hard Book microsoft has unnecessarily complicated the resource allocation feature.
Also once the resource is hard booked, system still adds to the booked hours, if the same record is soft booked. There seems to be many irregularities and bugs in the feature.
But i really appreciate the response on this issue as well as the resource request workflow ones.
Kind Regards
