ISSUE :
  In a multiple client project – Bucket method, the project structure is assigned to all clients. When a user picks this client in their timesheet, only certain tasks should show up from this project which will be related to that client.

RESOLUTION :
  It is not possible to map individual tasks to each client in a Multiple client project – Bucket Method. If a customer wants to assign Task 1, 2, 3 to client 1 and Task 4, 5, 6 to client 2 belonging to the same project, this is not achievable.
  The only available option is to create single client project and assign only Task 1, 2, 3 to this project and let Client 1 be the only client. Then likewise, create another single client project and assign Task 4, 5, 6 and Client 2 to this project.
  Now when a user picks up Client 1, he will only see Tasks 1, 2, 3 available for him. This setup is not achievable with Multiple Client project – Bucket Method.
