PA : how do i map project to project task( reporting )

[pramn]

Hi Team , 

Creating break down for Project task, whenever we open the project, Project task should associate with particular project , 

How do i do that , also i find in project table the related list for project task , it means that's task is coming from different table ,

can someone guide me how do create the break down source  ?

Much appreciated for your help !

Please elaborate on your requirement? What are you exactly looking for? 
Projects are on the pm_project table and tasks are on the pm_project_task table, where the relation is created (OOB) through the parent field on the project task table. A project task is per definition associated with a project. 
What are you trying to achieve? Because a breakdown when you open a project, doesn't really make sense. Breakdowns are used in reporting capabilities.

Could you please elaborate the steps ?

because in demand table we have project associated  and requirement is user want to see report when he choses the project associated task should visible to them .

What is your report? 'If he choses the project....' what do you mean? Do you have a filter on the dashboard where this is on? Are you filtering a list? What are you doing? Because if you chose a project from a list report, the project opens and the tasks are right there.
