Setting up work effort that is different from Duration

It may sound bit confusing for many guys but let me try explaining it as simple as I can. I want to make a project with 1 week duration but the actual work time will be just 2hrs. In another words, I am having a week time to complete a task which can be done in just 2 hours. I can do it one , twice or in thrice effort in this entire week. Is that possible?

I am using MS Project 2003. Thanks for your helps.

First of all you must know that Work and duration are two different fields. That is: Work=Duration x Assignment Units. You will be able to enter 5d for duration in case you change the task type to "Fixed Duration" and later you can assign 2 hours in the work column. By doing this MSP will distribute this two hours of work over the five days.

Thank you LeonL! I believe this is what I needed.
