Project limits overview

Tasks

The maximum number of tasks per project is 5,000. A warning message displays when the number of tasks approaches this maximum. When the maximum is reached, an error message displays and additional tasks cannot be added to the project.

To avoid reaching this maximum, move tasks that are closed to another project designated for closed tasks. Reports on these projects may need to be adjusted.

IMPORTANT

For projects where tasks have a lot of dependencies, a performance degradation might occur in calculating the timeline or when working in the project.

For this reason, we recommend that the number of tasks in projects with complex dependencies should be much lower than the maximum allowed of 5,000 tasks.

Some examples of task dependencies that might influence or prevent recalculating the project’s timeline are:

• Number of children
• Multiple levels of task indentation
• Number of predecessors
• Multiple assignments

Issues

The maximum number of issues per project is 10,000. A warning message displays when the number of issues approaches this maximum. When the maximum is reached, an error message displays and additional issues cannot be added to the project.

To avoid reaching this maximum, move issues that are closed to another project designated for closed issues. Reports on these projects may need to be adjusted.

Durations

The maximum duration of a project must be 15 years for Workfront to automatically calculate its timeline. A warning message displays when the project duration approaches the maximum. When the maximum is reached, a warning message displays and the automatic timeline calculations no longer occurs.

The automatic timeline calculations will resume as soon as a project's duration is reduced below 15 years by adjusting the dates of the tasks in the project.

Timeline calculations

Workfront does not perform automatic timeline calculations for projects that haven't been updated in 6 months and will not resume until an update is made.

For projects that haven't been updated in 3 months, Workfront performs timeline calculations weekly instead of nightly.
