Today at work I had a request from my customer for assigning him to all the tasks of all the projects. Though the number of projects are less but tasks are more then 700 per projects. And I was kind of WTH!
Then I find out following option to - Assign a project server resources to multiple tasks in Microsoft Project 2007.
1. Select all the tasks your want to add your resource.
2. Goto Tools -> Assign Resource
3. Select resource you want to assign to all the selected task.
4. Click on Assign.
5. Assign button will go gray and click on Close.
6. That is it!
