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 Created field contains the date and time when a resource was added to the project.
How Calculated Microsoft Office Project assigns the current date to this field based on the current date set in Microsoft Windows.
Best Uses Add the Created field to a resource view when you need to see when resources were added to the project. This can be particularly useful if you have a large number of resources and you want to filter for resources added to the project within a certain time frame.
Example You need to update the billing code for all the resources that were added to your project after June 30. Use the Created After filter to view all resources with a date in the Created field that falls after June 30.
