I'm setting up all my resources in the resource sheet (MSP2010) and find that the "available from and to" dates seem to work in a strange way (either that or I'm trying to make them do something they're not designed to do).

My resources BECOME available for use (at 50%) on a certain date.

Lets say I can have "Brian" from the beginning of May, to work on my project. Obviously, the relevant line on the resource sheet should show "Available from May 1st at 50%".

Instead, it seems that Brian is available UNTIL ("available to") 30th April at zero percent - which is technically correct, but pretty counter-intuitive in my opinion, and tells me nothing about his availablility AFTER the beginning of May.

Is there any way to make the resource sheet show what I'm looking for?

thanks
Guy
