Get only a subset of tasks, using Project Server 2007 PSI

[Jugdish]

Hi, this is a newbie question as I've just gotten started with the
Project Server 2007 PSI. I've got a project that contains about 5000
tasks, and I would like to get only a subset of those tasks. How do I
do this using the PSI? In reading through the docs, I see the
"ReadProject" and "ReadProjectEntities" methods in the Project web
service, but when I call these methods they return every single item
(a LOT of data), and there is no option to include a filter on those
methods, as far as I can tell.

What I'm really trying to do is return all of the child tasks of a
specific task (and really, all I need from them is the "TASK_NAME"
field for each). Seems like it should be doable, I just don't know
how.

Thanks for your help!

One way to do what you want would be to determine the GUID of the
Summary Task and then iterate through the Tasks table, pulling out any
tasks that have a TASK_PARENT_UID matching the GUID of the summary task.

I believe you could also use the Select() method inherited from
DataTable, or LINQ, although if you use LINQ you will need to use the
AsEnumerable() method discussed here:
