The Planned Work feature enables project plans to be fixed regardless of actual time tracked against a project. By keeping a project plan fixed , you can improve your future project planning by comparing the difference between planned time and actual time.
Enabling the Planned Work feature renames the Estimated Work field to Calculated Work on project records. A Planned Work field is added to project and project task records. When planning a project, planned work is entered on project or project task records. If you enter planned work on project tasks, the sum of the hours entered rolls up to be displayed in the Planned Work field on the project record.
IMPORTANT NOTE:
When using Planned Work, planned time entries are not converted to actual time entries, they remain in NetSuite as planned time. If you also use Advanced Project Profitability, this can result in a duplicate calculation of your committed costs. It is recommended that you ensure your custom profitability calculations do not have Planned Time enabled on the Settings page.
