Data Type Yes/No (Yes/No field: A type of field with content set to either Yes or No; also known as a Boolean field or a True/False field. For example, the Recurring field indicates whether the task is a recurring task.)
Entry Type Entered (entered field: A field in which you may type or edit information. This is in contrast with a calculated field, in which Project calculates and enters information.)
Description The Level Assignments field indicates whether the leveling (leveling: Resolving resource conflicts or overallocations by delaying or splitting certain tasks. When Project levels a resource, its selected assignments are distributed and rescheduled.) function can delay and split (split task: A task whose schedule is interrupted. For example, a two-day task that does not require contiguous work might be split so that the first day of work is scheduled for Monday, and the second day is scheduled for Thursday.) individual assignments (rather than the entire task) in order to resolve overallocations (overallocation: The result of assigning more tasks to a resource than the resource can accomplish in the working time available.).
Best Uses Add the Level Assignments field to a task sheet when you want to control leveling of task assignments directly on the sheet. Click Yes in the Level Assignments field when you want leveling to be able to delay and split individual assignments within the task. Click No in the Level Assignments field when you want to keep all assignments together when leveling occurs.
Example You have six resources assigned to a task, but only one resource is causing the overallocation. Click Yes in the Level Assignments field for this task, and only the one overallocated assignment will be leveled.
Remarks The default for the Level Assignments field is Yes. However, for all recurring tasks, the default is No.
For the Level Assignments setting to take effect on selected tasks, be sure that the project settings enable assignment leveling. You can do this in the Resource Leveling dialog box.
Because leveling individual assignments can increase the duration of a task, if you've specified a task as a fixed-duration task, the Level Assignments field is set to No and is disabled.
