Lookup fields - whats the trick????

Hi,

I've currently developed/developing a powershell cmdlet for some of the vsm api functions.. including the CMDBItemCreateRequest.

I have an entry that looks like "Server" for CMDBEntityType however if I pass Server to the lookup lCMDBEntityType it returns nothing.. using ~1234 works fine..

I haven't managed to find the query looking through the std queries to work out how it does the lookup.. but I always seem to have issues doing a lookup when its under a nested list..

IE..

Hardware > Server

What am I missing?

Or how can I use the ExecuteQuery to get me a list of valid entries / ID's?

Thanks

David
