Data Type Date (date field: A type of field whose content is a date. Examples include the Baseline Start and Early Finish fields.)
Entry Type Calculated (calculated field: A field in which the value is determined by Project based on information in other fields. Project may recalculate the value automatically or when you specify, depending on your choice of calculation settings.)
Description The Preleveled Start field contains the start date of a task as it was before resource 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.) was done.
How Calculated Before Microsoft Office Project levels resources, it saves the start dates for tasks in the Preleveled Start field.
Best Uses Add the Preleveled Start field to a task view if you want to examine the effects of resource leveling on your project's start dates.
Example Two resources in your schedule were overloaded, so you applied resource leveling to the project. You now want to see the effects of the leveling on your task start dates. You add the Preleveled Start field next to the Start field in the Task Sheet view to make your comparisons.
Remarks You can use the Leveling Gantt view to see the preleveled start date shown with the preleveled Gantt bars. Once you've leveled the project, specific tasks will have preleveled start dates that you cannot remove.
