How to Define Task Dependencies in Odoo 18 Project

After the creation of all the tasks, we can now set the task dependency in Odoo18.To get started, select and open a task. A new tab named Blocked By can be seen which has become visible due to the activation of the dependency feature.  Under this tab, we can mention the task that needs to be completed before this task can be started. It means that this task has been blocked by the task given under this tab.

Under this tab, click on Add a Line and select the required task from the list.

How Task Dependency Works: Blocking Tasks in Odoo 18

The Requirement Gathering task has been added over here, so according to this configuration, the task Project Planning has been blocked by the task Requirement Gathering, that is Project Planning task is dependent on the Requirement Gathering task and only when it is completed the task Project Planning can be started. Before proceeding, the task’s status is Waiting, and a waiting symbol appears at the top. Clicking View will show you any tasks that are currently preventing this one from moving forward..

In that task, a smart button named Blocked Tasks will appear, which shows the tasks that have been blocked by it.

In order to have a visual representation of the tasks, navigate to the Gantt View of the tasks for the respective project.

Task dependency can also created from the Gantt chart view.

The arrow indicates that the task can only be in progress once the previous task has been completed.

Odoo 18: Dependent Tasks Wait for Completion

Since the task dependency has been added, the task which is dependent , in our case the task named Project Planning, cannot be changed to ‘In Progress’ until the task on which it depends is Done or Cancelled.

Now let us go to the task named Requirement Gathering and mark it as Done.

Once this task has been completed and marked as Done, the dependent task, i.e., Project Planning, can be started.

As shown in the above image, the task state has been changed from Waiting to In Progress, and the Blocked By task has been marked as Done.

This task dependency in Odoo18, and its feature can also be applied to Sub-tasks. To add a sub-task, go to ‘Sub-Tasks’, click ‘Add a line’, and put in the title
