# Modify a project task dependency

# Modify a project task dependency {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Modify a dependency when editing the tasks that are linked in the dependency, the dependency type, or the lag time.

## Before you begin

Role required: it_project_manager

## About this task

Project task dependencies are saved on the Planned Task Relationship
\[planned_task_rel_planned_task\] table. You can access dependencies from the planning
console.

## Procedure

1. Double-click a dependency on the Gantt chart of the [planning console](https://servicenow-prod.fluidtopics.net/gW_cPPq9eZH~xOWmFjHaVg "The planning console is a centralized interface for the Project Management application.").
2. On the form, fill in the details.  
   For more information, see [Planned Task Relationship form](https://servicenow-prod.fluidtopics.net/YAG4VrpuNii7Xue4ZCjmCA "Learn about the fields of planned task relationship form.").  
   Figure 1. Planned Task Relationship form
3. Select Update.  
   You can view dependencies in the Project Task related list on a Project or Project Task form and from the Project Tasks list on the workbench. These columns show the dependencies:
   * The Dependency column shows the successor task in the relationship.
   * The Dependencies column shows the dependency value. See [Predecessor dependencies in the planning console](https://servicenow-prod.fluidtopics.net/Sd6Ow6kCA6BOtM6tdn~EMw "In the WBS section of the planning console, you can create dependencies between tasks by specifying a series of values.") for a description of what you see in this column.
