Symptoms

ACTUAL BEHAVIOR
---------------
When the "Schedule automatically when a change affects a date" scheduling option is selected and multiple projects are opened, a change in a single project results in all open projects to be automatically scheduled.

Note:
 - The time it takes for the automatic scheduling operation to complete can be perceived as a performance issue since all open projects are being scheduled even though only a change in a single project is made.
 - This performance degradation is compounded when latency is introduced into the connection between P6 Professional and Cloud Connect server.

EXPECTED BEHAVIOR
-----------------------
When the "Schedule automatically when a change affects a date" scheduling option is selected and multiple projects are opened, making a change in a single project should only trigger automatic scheduling to occur against the project where the change was made and not all projects which are opened (unless required) due to inter-project dependencies.

STEPS
-----------------------
The issue can be reproduced at will with the following steps:

  1. Open 5 projects
  2. Select Tools, Schedule
  3. Select Options (in scheduling window)
  4. Select the option "Schedule Automatically when a change affects the dates"
  5. Select "Close" to close the scheduling options then "Cancel" to close the schedule window
  6. Select File, Close all to close the 5 open projects
  7. Open one of the five projects
  8. Select Project, Activities
  9. Perform some action to initiate the auto-scheduling feature
  10. Note the time it takes to complete the task
  11. Browse to the Projects View
  12. Open all 5 of the projects (originally opened in step 1)
  13. Select Tools, Activities
  14. Complete the same action as step 9 to initiate the auto schedule feature
  15. Note the time it takes to complete the task
  16. Note the time difference between step 10 and step 15

BUSINESS IMPACT
-----------------------
The issue has the following business impact:
Due to this issue, the application can be perceived as unusable due to the performance degradation which occurs while the schedule operation completes.
