How to see total duration of the main project?

Hi,
I test many sub tasks in one main branch.
When I change the size of line gantt than duration of the line is changing in left panel. But the main branch duration is not chaning? How can I see main branch time when I change the sub tasks and more sub tasks?

Hello Mucip,
It depends on the task type.
If the parent task has the task type, you can set any dates regardless of the dates of the child tasks:

If the parent task has the project type, it always depends on the dates of its children:

You can check the difference in the following snippet:

Dear Ramil,
