You can configure the default dependency type and how dependencies behave across tasks.

1. Click  in the upper-right corner and select Portal Configuration.
2. Navigate to Task & Timesheet.
3. In the Task Settings tab:
   
1. Select a value from the Default Dependency Type drop-down.
   
1. This defines the dependency relationship between tasks by default when tasks are connected in the Gantt Chart. The dependency type can be changed later, if required.
   
2. Choose a Dependency Link Type.
   
1. Hard Link: Successor task dates are automatically adjusted based on changes in the predecessor task.
   
2. Soft Link: Successor tasks remain unchanged even if the predecessor task is modified.
   
4. Click Update.
   

For example, when the predecessor task Design is moved to March 13, the successor task Development is automatically moved to March 14 in a hard link, whereas it remains on its original date in a soft link.
