Retrieve non approved work from Project 2007

[RainieroDin]

Hi, I need to retrieve the amount of work which has not been approved yet by
the project managers in project 2007 (through webservices or directly from
the database). I already tried with the Project Server report pack, but
coudln't find the information there. The Statusing webservice provides the
ReadAssignmentHistory method, and the ASSN_CHANGE_DATA column seems to
contain the required information (its value is changed every time I report
work), but it's a byte array, is there a way to extract the information from
this column? Should I try something else? Thanks in advance

Any ideas please? I tried in the Project Server DG and they pointed me out
that this could be the right place to ask, any help will be appreciated...
Thanks
