The Duration1 through Duration10 fields are custom fields that store any task, resource, or assignment duration information you want.
There are several categories of Duration1-10 fields.
Data Type Duration
Duration1-10 (task fields)
Entry Type Calculated or entered
Best Uses Add one or more custom duration fields to a task view when you want to enter custom task duration information that is not already provided by a standard Project duration field.
Example You can enter the longest estimated duration for a task in the Duration1 field and the shortest estimated duration in the Duration2 field.
