# Pre-date a project task

Move the planned start date of a task before the planned start date of a project. Adding a pre-dated task allows you to accommodate tasks which need to start before the planned start date of a project.

## Before you begin

You should have created or added project tasks to your project.

Role required: it\_project\_manager

## About this task

Before pre-dating a project task, note the following conditions:

-   The property project.rollup\_project\_start\_date should be set to true.
-   Pre-dating a task's planned start date also moves the project's planned start date.
-   The start date of a child task can't be moved before the parent task's start date. For example, a parent task with Start no earlier than constraint starts on the 20th and the child task starts on the 30th. The start date of the child task can only be moved up to the 20th.

## Procedure

1.  Navigate to **All** > **Project** > **Projects** > **All**.

2.  Select the project from the list.
