Overriding Task Attributes on Human Activity Level 
When you assign a task to a human activity, you can override the defined task attributes on the human activity level. You override task attributes on the human activity level when you want to use the same task in different human activities in the process model. Overriding the task attributes means that you define different settings for the task attributes for each human activity instead of creating a new task for each human activity.
You can override the following task attributes on human activity level:
Priority
Potential and excluded owners
Activation time
Start deadline
Completion deadline
Expiration time
You override task attributes using the Properties view of a human activity.
